Will temperatures affect the admixture while in a liquid state?
Yes, cold temperatures can affect the performance or viscosity of Krete admixtures. While some products will lose performance after freezing, others may only need reheating to achieve performance. Refer to the Product Data Sheet of each product for storage requirements.
What's the difference between primary and secondary efflorescence?
Primary efflorescence is a natural by-product of the cement hydration process. When cement reacts with water, it releases calcium hydroxide as a reaction by-product. When this calcium hydroxide makes it to the surface of the concrete, it reacts with carbon dioxide in the atmosphere. This reaction creates calcium carbonate, better known as efflorescence, the white chalky deposition on the surface of concrete. Primary efflorescence is very uniform in nature, meaning it appears in the form of a white haze or "dull" colors.
Secondary efflorescence occurs when external water or soluble salts penetrate the concrete after it has cured. These foreign atmospheric conditions liberate calcium hydroxide trapped in the concrete and bring it to the surface. After it reaches the surface, it reacts with carbon dioxide to form calcium carbonate. Secondary efflorescence tends to occur in very localized areas of the concrete.
Which Krete products protect against primary and secondary efflorescence?
KreteControl: KreteControl products are non-aqueous, 100% reactive chemicals formulated to provide superior primary and secondary efflorescence control. These products cause a chemical reaction immediately after introduction to the concrete mix in order to turn free calcium hydroxide into insoluble pore-pluggers, locking these particles into the concrete matrix and significantly reducing primary efflorescence. In addition, KreteControl products react with water in the mix to create water repellent chemistries to further seal the concrete unit, protecting it from secondary efflorescence for the entire life of the concrete product.
KreteGuard: KreteGuard products are aqueous water repellent and efflorescence control chemicals that work in various ways depending on product needs and functionality. This product line includes static-repellents and highly-reactive water repellent chemistries.
What is the advantage of non-aqueous admixtures?
Our KreteControl product line consists of all non-aqueous chemicals. Krete recommends adding these materials with the aggregate, at the beginning of the concrete batch (as opposed to traditional aqueous admixtures added with the final water). By incorporating the admixture with the aggregates, the aggregates are coated with water repellent and efflorescence control chemistries, acting as a "carrier" throughout the concrete matrix. This allows for additional mix time versus traditional admixtures and results in uniform dispersion of high performance admixture.
How can I acquire Safety Data Sheets for Krete products?
All Krete products are shipped with a Safety Data Sheet attached to the label. Current Krete customers are able to acquire additional electronic copies by calling the Krete Customer Service Department and submitting a request.
