Concrete deterioration is one of the most concern matters in construction world. The concrete deterioration such as efflorescence should not be ignored. The efflorescence is a deposit salts, usually white, formed on a surface of concrete. The efflorescence is not a major problem that leads to structural defects but it can build unattractiveness to the structure such as brick wall and concrete mortar. The way to prevent the efflorescence occurrence is by studying the results of testing such as absorption and efflorescence itself to reduce the efflorescence. The non-modified cement system can reduce the efflorescence but cannot avoid it because of the reaction of cement hydration itself. This study is to prove that by using a modified cement system such as Pulverized Fly Ash (PFA) and Polymers (water based latex grade 29Y46), the efflorescence of the mortar can be prevented. The results from this study proved the modified mortar which is a sample with PFA and Polymers has higher strength, durability, and less efflorescence compared with the non-modified cement system.
