Abstract EN
This study looked at the effects of three types of additives: limestone powder, Arabian gum AG, and polyvinyl alcohol (PVA), on White Cement Mortar's Physical and Mechanical Properties the mixing ratio for dry shrinkage was 1: 2.
(Cement: sand) while for other tests, it was 1: 2.75 (cement: sand).
The limestone powder proportions are (5% , 10% , and 15% ) by weight of white cement, while the AG ratios are (0.2, 0.5, and 0.8) % by weight of white cement, the polyvinyl alcohol ratios are (2% , 4% , and 6% ).
This study was focused at the compressive and flexural strength of the modified mortar, as well as water orption and drying shrinkage.
According to the findings, utilizing of limestone powder as additive in white cement mortar is not advised.
Since it had the negative affect on dry shrinkage of the mortar.
Furthermore, polymer additives such as AG and PVA significantly increase the reduction of ability of forming crack in white cement mortar.
Furthermore, the optimal additive percentages of AG and PVA are 0.5 percent and 6% , This study looked at the effects of three types of additives: limestone powder, Arabian gum AG, and polyvinyl alcohol (PVA), on White Cement Mortar's Physical and Mechanical Properties the mixing ratio for dry shrinkage was 1: 2.
