ConcreteAdditives.net is an independent reference on concrete admixtures, supplementary cementitious materials, fibers and integral pigments: no company pays for placement, every value names its primary source with edition or date, and reported errors are corrected wherever the value appears.
Eleven groups of primary sources stand behind every value, from ASTM C494/C494M-24 to REACH Annex XVII entry 47. Requests go to independent suppliers and providers, form data is kept for 24 months, and reported errors are corrected on every page.
Which Topics and Readers Does ConcreteAdditives.net Serve?#
ConcreteAdditives.net covers what producers, specifiers and contractors add to a concrete, mortar, grout or shotcrete batch: chemical admixtures, supplementary cementitious materials, fibers and integral pigments, plus the standards, tests, properties and special concretes that depend on them. The readers are producers, specifiers, engineers, lab staff, contractors, distributors and procurement teams, and each family of concrete additives is listed on one overview page, concrete additives.
"Concrete additive" is the site's umbrella term, not a term defined by ACI, ASTM or EN.
How Does ConcreteAdditives.net Keep Editorial Independence?#
ConcreteAdditives.net keeps editorial independence by selling no product, accepting no payment for placement in its content and calling no company recommended, preferred or verified.
Where does the site's revenue come from?#
The site's income is to come from passing supplier and provider requests to independent companies and, later, from display advertising below main content; neither source buys a mention, a value or a position on a page.
The site shows no ads at present. Once added, advertising never appears above main content and never on trust pages or tools.
When do manufacturers and trade names appear on a page?#
Overview, family and application pages name no company; a manufacturer appears only as the source of one product's value, named in the same sentence as that value.
A brand question is answered by what a type in ASTM C494 or a table in EN 934-2 requires and where the data sheet declares it. Supplier types and the way to compare their data sheets are covered under concrete admixture manufacturers and suppliers.
Which Primary Sources Stand Behind Every Value?#
Every value on ConcreteAdditives.net comes from 11 groups of primary sources, the standards bodies, code writers, agencies and registers that issue the requirement, the rule or the substance record, and a newer official text replaces an older value.
The 11 source groups and what each supplies are listed below.
| Source | What we take from it | Example as written on the site |
|---|---|---|
| ASTM International | specifications and test methods, editions, status, types and classes | ASTM C494/C494M-24, active, Types A, B, C, D, E, F, G and S |
| CEN and national standards bodies (BSI, DIN, SIST) | EN product and concrete standards, editions | EN 934-2:2009+A1:2012; EN 206-1:2026 |
| BIS (Bureau of Indian Standards) | IS standards, status, reaffirmation | IS 9103:1999, active, reaffirmed 2018, with two amendments |
| ACI (American Concrete Institute) | building code and guidance documents, edition and clause | ACI CODE-318-25 Table 19.3.2.1 |
| AASHTO | US transportation test methods | AASHTO T 402-23 with ASTM C1876-25 for bulk resistivity |
| FHWA | US federal research reports and technical briefs | FHWA-HIF-20-085 (2020) |
| EUR-Lex (EU Official Journal) | EU regulations, entries and application dates | Regulation (EU) 2024/3110, applicable from 2026-01-08 |
| ECHA | CLP classification, REACH restrictions and registrations | REACH Annex XVII entry 47; calcium chloride hazard line |
| eCFR and OSHA | US federal rules | 29 CFR 1926.1153 |
| PubChem | substance identity (CAS, formula) | calcium nitrite CAS 13780-06-8, not calcium nitrate CAS 10124-37-5 |
| Peer-reviewed journals and research reports | study results, named with authors, institution and year in the sentence | FHWA-HRT-06-118 durability factors |
| Not counted: manufacturer data sheets | one named product's declared value | "typical value of {product}" |
A manufacturer data sheet describes one product and never overrides a standard. A value that no primary source supports is not published, and unauthorized copies of standards are never cited or linked.
How are standard editions, code clauses and regulations cited?#
Every standard carries its full designation, edition and status, every code value its edition and clause, and every regulatory value its instrument, entry and date, for example ASTM C494/C494M-24 (active) and ACI CODE-318-25 Table 19.3.2.1. Every standard on the site with its edition is indexed under concrete admixture standards.
The table compares the citation formats with one real example each.
| Item | Written as | Example |
|---|---|---|
| Standard, active | designation, edition, status | ASTM C494/C494M-24, active, eight types A to G and S |
| Standard, withdrawn | year and replacement | ASTM C1017, withdrawn 2022, no replacement |
| Standard limit | edition and clause, basis named | EN 934-2:2009+A1:2012, 3.2.1: admixture dose not more than 5 % by mass of the cement |
| Code limit | code, edition, table, basis | ACI CODE-318-25 Table 19.3.2.1: water-soluble chloride for nonprestressed concrete in Exposure Class C2 at most 0.15 % by mass of cementitious materials |
| EU rule | instrument, entry, value, basis | REACH Annex XVII entry 47 (Regulation (EC) No 552/2009): soluble chromium VI at most 2 mg/kg (0.0002 %) of the total dry weight of the cement when hydrated |
| US rule | CFR section, value, effective date | 29 CFR 1926.1153: respirable crystalline silica PEL 50 µg/m³ 8-hour TWA, action level 25 µg/m³, effective 2016-06-23 |
| Hazard line | Annex VI or notified, with index | calcium chloride: "Harmonised CLP Annex VI (index 017-013-00-2): Eye Irrit. 2, H319"; sodium dodecyl sulfate (sodium lauryl sulfate): "No Annex VI entry; ECHA C&L notified classification: H302, H315, H318" |
| Unit conversion | metric first, factor stated | 1 fl oz/cwt = 65.2 mL/100 kg; 1 kg/m³ = 1.6856 lb/yd³ |
How are standard requirements, product values and study results told apart?#
A standard requirement is written with its standard, edition and clause, a product value as the typical value of one named product, and a study result with the study named in the sentence. The EN 934-2:2009+A1:2012 clause 3.2.1 limit of 5 % by mass of the cement is a requirement. In FHWA-HRT-06-118 (Tanesi and Meininger 2007, water-cement ratio 0.45), the non-air-entrained control reached a durability factor of 14.4 %, and Vinsol mixes at 2.7 to 4.7 % fresh air reached 85.7 to 93.5 %, which is a study result.
How are dosages, units and safety statements written?#
Every dosage carries its basis, % by mass of cement or of total cementitious materials, mL/100 kg (fl oz/cwt) of cementitious material or kg/m³ (lb/yd³) of concrete, and every quantity is metric first with US customary units in parallel. The conversion factors are 1 fl oz/cwt = 65.2 mL/100 kg and 1 kg/m³ = 1.6856 lb/yd³.
A hazard line follows one rule: the harmonised CLP Annex VI entry where one exists, else "No Annex VI entry; ECHA C&L notified classification" with the notified codes, else the product safety data sheet. Identity comes from PubChem, so calcium nitrite (CAS 13780-06-8) is not calcium nitrate (CAS 10124-37-5). The site gives no medical advice and cites the product safety data sheet and the regulator.
Where Do Supplier Quote and Provider Requests Go?#
Quote requests and provider requests sent through ConcreteAdditives.net go to independent suppliers and providers; no company pays for placement, and no company is named as a partner. Two request tools exist, listed below.
- Request quotes from concrete admixture suppliers: Send your specification to independent suppliers.
- Find a mix design, testing or specialty placement provider: Your request goes to independent providers of mix design, testing or specialty placement.
Form data is kept for 24 months. Rights and retention are set out in the privacy policy.
The forms never name a company and promise no response time and no number of quotes. The line printed under every form reads: "Independent suppliers and providers receive requests; none pays to appear here (editorial policy)."
How Is an Error Reported and Corrected?#
An error is reported to editorial@concreteadditives.net, checked against the issuing body's current text and corrected on every page that states the value. A report is checked fastest with 4 items, listed below.
- Page URL
- The value or sentence
- The source, with edition or date
- The corrected wording
The same address and a form are on the contact page. No reply time is promised.
What changes on a page after a correction?#
A corrected page shows a new reviewed date, and every other page that stated the old value is corrected with it.
When Are Pages Rechecked After New Standards and Regulations?#
Pages are rechecked when the text behind a value changes: a new ASTM, CEN or BIS edition, a new ACI code cycle, a REACH or CLP amendment, and the yearly update of each dated cost range. Two dated examples: ASTM C618-26 is active since 2026-08-11, and EN 206-1:2026 (CEN approval 2026-01-19) supersedes EN 206:2013+A2:2021, with conflicting national standards withdrawn by September 2026.
Market sizes appear only as analyst estimates with publisher and year, and prices only as dated public-record ranges. Dated standard and regulation changes appear under concrete additives news.
What Does ConcreteAdditives.net Not Publish?#
ConcreteAdditives.net publishes no brand rankings, no product reviews, no homeowner tutorials and no single market-size figure stated as fact. Curing compounds, sealers, repair mortars, grouts and additives dosed at the cement mill are outside the scope of this site.
Who writes the pages on ConcreteAdditives.net?#
Does the site rank or recommend suppliers?#
No: no supplier or provider is ranked or called recommended, preferred or verified, and requests go to independent companies.
Are homeowner tutorials or product reviews published?#
No: pages are written for producers, specifiers and contractors, and a residential question is answered at specification level.
Does ConcreteAdditives.net sell admixtures?#
No: ConcreteAdditives.net sells no admixture or other product.
Does a safety statement replace the product safety data sheet?#
No: the product safety data sheet governs, and each safety statement names the regulator or data sheet behind it.
