In concrete with low strength grade, limestone powder can be used instead of cement to achieve comprehensive utilization such as reducing cement consumption, reducing hydration heat and rationally utilizing industrial waste. This is measured by experiments. The influence of limestone powder with different mass percentage instead of cement on concrete strength was studied. The results show that with the increase of limestone powder replacing cement, the early compressive strength and splitting tensile strength of concrete blocks tend to decrease. However, the recession tends to increase. The reason for this phenomenon is that limestone powder is an inactive substance. Through this experiment, we found an equivalent way to save money.
Through the introduction of the above scientific research results, we can temporarily or use limestone powder to replace other products in some other uses, and also achieve the same effect, which provides more choices for our industrial production and construction site materials and solves your immediate problems.
