Concrete: Cement Substitutes - GGBS, PFA and more

Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume. Silica fume is a by-product from the manufacture of silicon.

What Is Concrete | 31 Different Types of Concrete

What Is Concrete? Concrete is the final product resulting from mixing cement, aggregates (including sand), water, and mixtures. It is initially malleable in its "wet" state and solidifies over time, gaining strength and durability. The first use of concrete was […]

Cement & Concrete

Cement and Concrete . In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

New technology captures the carbon naturally emitted during the cement manufacturing process and injects it back into the concrete mix during mixing. Encourage concrete suppliers to use carbon sequestration/CO 2 injection methods. Specify hard, clean, and strong aggregates

Alkali–silica reaction - Wikipedia

The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.. This deleterious chemical reaction causes the expansion of the altered aggregate by the ...
