EXPERIMENTAL STUDY ON EFFECTS TO CORAL SAND CONCRETE COMPRESSIVE STRENGTH OF RAW MATERIALS

According to the method of a full factorial experiment, experiments were carried out to compare the cube compressive strength of coral sand concrete, focusing on three factors and two variables. The effects of different cement, fine aggregate and sea or fresh water for concrete curing on the compressive strength are analyzed. The results show that the coral sand concrete with sulfate resistant cement and sea water has relatively good performance and high strength.
