Experimental study on the optimization of the mix ratio of plant concrete cementitious materials

In view of the problem that the alkalinity of concrete planting slope protection is high and cannot meet the requirements of planting, taking into account the compressive strength of concrete, by selecting different admixtures, the trial matching test of cementitious materials and measuring their corresponding properties are optimized. The results show that it is feasible to use aluminum sulfate cement as the main part of the cementitious material; The addition of mineral admixture to the cementitious material can reduce the alkalinity, but the effect is not very obvious; Gypsum has a higher alkali control capacity than mineral admixture, and the resulting compressive strength of the concrete has reached a more ideal situation. The test shows that 60% aluminum sulfate cement mixed with 5% silica ash, 20% gypsum, and 15% mineral powder can make the alkalinity and compressive strength of the concrete reach
