Mineral Admixtures on Concrete

Used to improve the performance of concrete, industrial waste or mineral fine powder with a certain degree of fineness added in the concrete mixing process, it is an auxiliary cementing material that replaces part of the cement consumption.

How to Process Concrete Admixtures

To give full play to the pozzolanic activity, morphological water reduction effect and micro-aggregate filling effect of active admixtures and inactive admixtures, and improve the quality and performance of concrete, admixtures must have a finer particle size and larger than cement Specific surface area.

Research and Application of High-Strength and High-Performance Concrete

High-strength concrete has a low water-binder ratio and a large amount of cementitious materials, which leads to an increase in hydration temperature, so plastic shrinkage and self-shrinkage. Although high-strength concrete has a higher tensile strength, it has a high elastic modulus, which will cause higher tensile stress under the same shrinkage and deformation, so the risk of cracking in the early stage and during use cannot be ignored.
