| Abstract: | Method and mechanism of preparing high strength concrete mixed with composite micro-aggregates (fly-ash and fine zeolite) and superplasticizer were studided. The results show that the addition of composite micro-aggregates to concrete can improve the structure of the mortar and interface, and greatly increase the compressive strength of concrete. By adding the composite micro-aggregate consisting of fly-ash and zeolite, the 28-day compressive strength of the concrete reaches 75. 5 MPa, when the cement quantity in the concrete is 460 kg/m3 |
