Shrinkage Cracking Ring Tests of Concrete with Compound Mineral Admixtures
Shrinkage cracking is the direct cause which leads to the deterioration of durability and integrity of concrete. In this paper, ring-test methods are used to study the early age cracking characterization of compound mineral admixtures concrete which includes steel slag, blast furnace slag and fly ash. The effect of compound admixtures on cracking characterization of concrete is discussed, restraint stress caused by concrete shrinkage and cracking age are analyzed. Through the comprehensive consideration of the free shrinkage strain, creep, restriction factors on the effect of the cracking of concrete specimens. The results show that suitable proportion mineral admixtures can be used to reduce cracking in concrete. The risk of cracking can be estimated for compound admixtures concrete, so that it will improve the durability of concrete structures.
