| Abstract: | From many kinds reasons that cause contraction,three factors(the plumping agent,the pulverized coal ash and the water ratio)which affect the contraction concrete`s performance is discussed emphatically.By experiment research on the concrete test sample which mixed the different quantity plumping agent,the pulverized coal ash as well as the changed water ratio,the influence which three factors produced to concrete expansion rate and intensity is obtained finally.Thus the mixture ratio which is a suitable pro... |
