- Abstract
By making use of the optimized particle grading and excitation principle, as ynergist capable of replacing part of cement is developed based on multi-component mineral material, and its effect on concrete performance, mechanical properties and durability was studied. At the same time, the microstructure of the material was analyzed by scanning electron microscopy (SEM). Studies have shown that compared with the control group, the mineral material synergist can improve the working performance of concrete and reduce its fluidity loss; when the amount of cement substitution does not exceed 15%.the mechanical properties of concrete are improved at all ages, and 10% was the best. The compressive strength and flexural strength of the 28d age increased by 5.8% and 18.0% respectively; the penetration height decreased by 31.1 mm, the electric flux decreased by 19.5%.and the resistance to sulfate attack was also greatly improved.
