Compared to cement and water, the chemical reaction between fly ash and calcium hydroxide typically is slower resulting in delayed hardening of the concrete. Delayed concrete hardening coupled with the variability of fly ash properties can create significant challenges for the concrete producer and finisher when placing steel-troweled floors.
Masonry/MCP Admixtures. Euclid Chemical provides a range of admixtures to meet the needs of the block, paver, roof tile, hollow core slab and dry-cast pipe producers. These products are used to improve the production efficiency, performance, and visual appeal of machine-made concrete products.
Concrete is not as likely to rot, corrode, or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the work-site which reduces costs. Concrete is a non-combustible material which makes it fire-safe and able withstand high temperatures.
The chemical resistance of concrete is highly limited. If exposure limits are exceeded, concrete surfaces can be durably protected with coatings. Sika offers a wide range of solutions to prevent the penetration of chemicals. Sika Solution: Sikagard®, Sikafloor® and Sikalastic®
Concrete Admixtures - Set Retardant Time: 02:27 Using a concrete admixture to delay the setting of the concrete gives the concrete finisher longer to apply the proper finish. Learn more about this concrete set retardant and see how it is used on a slab that will be textured.

Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing ...
Portland cement concrete is prone to drying shrinkage cracking. It is susceptible to attack by sulphates and has an undesirable reaction with certain aggregates (ASR). Generally, when one accelerates the gain in strength of portland cement concrete through finer grinding or chemical additives, there is a significant increase in drying shrinkage.
Masterbond High Strength Bonding Agent is a reemulsifiable Masterbond High Strength Bonding Agent is a reemulsifiable fast drying bonding adhesive that creates a long lasting chemical bond between cement plaster and existing concrete surfaces. It dries to a highly flexible film that not harden or crack on aging.
