Abstract: This study deals with the influence of Poly Ethylene Glycol (PEG) and Poly Acryl Amide (PAA) upon the characteristics of the cementitious brick and board for example setting time, flow-ability, bearing and bending strength, via. including 1, 3 wt.% of PEG400 as well as (PEG/PAA) as additives by cement weight. Also, it was investigated the characteristics of bulk density and water absorbing ability of ensuing produces. By blending the fly ash to cement, the cementitious samples of mortar had been made which were treated via. traditional technique (water based-treatment). Through, appending polyethylene glycol only plus the binary polymer mix (Polyethylene glycol/polyacrylamide) tovarious percentages of weight (1, 3%) of cement weight, the cementitious mortar of self-treated feature had beendone. The findings show that the self-treating strategy being utilized possesses constructive outcome on the work ability and quality of the mortar examples. Cementitious Mortar examples, treated via. treating technique showed better productivity bulk density diminishing. It can be noticed that, the execution of self-treating technique is superior to that of water-based treating. In this study the facts develop that indicates the self-curing utilizing in conditions as treating process by water can behard. Nevertheless, amid both study in gtreating techniques, self-treating mortar registered superior physical and mechanical characteristics than the mortar of water-based treating nature. Cementitious board and bricks were produced from the optimum results of 3 wt.% PEG400 and (PEG/PVA). It was found that the bearing strength of PEG 400 modified cementitious brick ranged from 26.38-27.24 MPa and its water absorption from 4.56-5.06 wt.% while the bending strength values of polymer blend modified cementitious board were within the range of 3.6-4.5 MPa which were higher than that of the reference cementitious board which equal to 1.9 MPa.
