English Abstract

The presented study examined the impact of Arabic gum (AG)on physical and mechanical properties related to ordinary cement mortarby cement'spartial replacement via various quantities of Arabic gum(0.1% , 0.3% , 0.5% , 0.7% , 0.9% ), the sample mortar's preparation was achieved with using 1: 2 ratio of cement to sand by weight, witha (0.5)water to binder ratio.

The compressive strength, flexural strength, and Workability tests were carried out on these five groups(G1, G2, G3, G4, G5) in addition to a reference group G0 that not contain Arabic gum, compressive as well as flexural strength tests were achieved after curing at early and standard age 7 and 28days, respectively.

The results specified that the compressivein addition to flexural strengths of samples of groups G1, G2, G3 mortars were increasing with the increase of replacement's ratio (0.1% , 0.3% , 0.5% ) and then decreased at G4 andG5 (0.7% and 0.9% ) and The best results were recorded at G3(0.5% replacement ratio) where enhancement of compressive strength17% and 16% for early and standard age respectively and enhancement of flexural strength 11% and 10% for early standard age respectively, the results of workability test refers to that the increase of the ratio of Arabic gum (AG) in the mortar increaseits workability, from SEM analysis indicated in sample G3were more homogeneous microstructure in comparison to the microstructure of G0.
