Abstract
The mechanical properties of the calcium sulfoaluminate cement, calcium aluminate cement, and cement systems containing CSA or CAC with ordinary Portland cement at a w/c ratio of 0.35 are to be evaluated and compared to those of ordinary portland type I/II and type III cement. The samples at the total cement binder of 446 kg/m3 and 390 kg/m3, cures at standard room temperature 23ºC are to be tested. The CSA and CAC influence the time of setting and compressive strength properties by showing the rapid strength increase at an early age. To obtain fresh properties, i) slump, ii) unit weight, iii) air content and iv) penetration (Time of setting) test, and hard properties, i) compressive strength, ii) tensile strength, iii) elastic modulus and iv) drying shrinkage test will be performed on several concrete mixes with different blends of cement contents.
