| Abstract: | Powdered emulsions and aqueous latex have been devel-oped and commercialized as cement modifiers for the past two decates in many countres.However in developping countries,the cost of these emulsions is too expensive to be accepted, especially the powered ones.The purpose of this study is to cut down the cost of powered emulsions polymer-modified mortars by using super-fine mineral powder so that these materials can be accepted easily by the enormous construction engineering,especially the binding and repair engineering.The properties of low content powdeed emulsions PCM were tested for flexural strength, compression strength, shear strength, shrinkage, w.terproofness, permeability, thermal compatibility, freeze-thavv durability and water resistance, It is concluded from the test results that the low cotent powdered emu-sion and super-fine mineral powder-modified mortars behave almost the same as that of ordinary PCM,and can be used in the same manner as ordinany PCM in practical applications. |
