In order to overcome these shortages of cement, limestone powder and fly ash are regarded as mixed materials and with clinker to form tri-cementitious materials.
The particle size distributions of these materials are shown in Table 1.
It means that the ratio of mixed materials should be appropriate.
Fig. 3 Effect of dosages of mixed materials on flexural strength Fig. 4 Effect of dosages of mixed materials on compressive strength Increasing of dosages of mixed materials will decrease flexural strength and compressive strength.
