Calcium carbide residue (CCR) is a waste by-product from acetylene gas production. The main component of CCR is Ca(OH)2, which can react with siliceous materials through pozzolanic reactions, resulting in a product similar to those obtained from the cement hydration process. Thus, it is possible to use CCR as a substitute for Portland cement in concrete.

allowable slump for concrete with superplasticizer

Slump for super-plasticized concrete doesn't mean much though, since the goal is a more liquefied mix. To me, measuring slump for any concrete mix serves as a sanity check more than anything. If you have 20 trucks with the same slump range, and the 21st truck is way off, could be indicative of a problem with that concrete before it is placed.

3 Ways to Reinforce Concrete - wikiHow

Dec 08, 2019 · To get a concrete strength of +- 40MPa, you need to add twice the amount of cement (by weight) compared to the amount of water. 1.5 x cement will yield a strength +- 20MPa. The more the cement content, the more surface cracks you will get. A superplastisizer reduces the amount of water and cement required leading to less surface cracking.
