The effect of Polyethylene glycol (PEG) and Polyacrylamide (PAA) addition, on the properties of the ordinary cement and mortar, such as setting time, flow-ability, compressive, and tensile strength has been studied by adding 1,3,5,7wt% additive of PEG400 and (PEG/PAA) by weight of cement. Flexural strength has been determined using center point bending system. Bulk density and water absorption of resulting products was tested. The plain mortar specimens were prepared from Portland cement and the other specimens from the mixing of fly ash with cement together, which were cured by conventional method (water based-curing). Self-curing mortar was performed by adding Polyethylene glycol alone and the binary polymer blend (Polyethylene glycol/ polyacrylamide) with different weight ratios (1,3,5,7)% by weight of cement. Results indicate that the self-curing method under work has positive effect on the workability and strength of the mortar specimens. Mortar specimens cured by self-curing method exhibited higher efficiency in decreasing bulk density. It is found that the performance of self-curing is better than that of water-based curing. The data developed in this study indicates that the self-curing could be utilized in situations where curing with water is difficult. However, between the two investigated curing methods, self-curing mortar recorded better mechanical properties than the water-based curing mortar. Web Site:  Web Site for Article
