Abstract

Premixed mortar which has been implemented for several civil works is also possible to be used in ferrocement structures. The requirement of compressive strength for ferrocement mortar is 30 MPa, meanwhile premixed mortar is commonly lower than that. The objective of this study is to evaluate the effect of steam curing and cement addition on the flexural and compressive strength of premixed mortar regarding to ferrocement requirement. Specimens were made from premixed mortar of SIKA with ratio of 1:0,35 of water by volume. The variables were ages of samples (1, 3, 7, 14, 21, and 28 days), percentages of cements addition (0%, 10%, 20%, 30% and 40%) and admixture used. All specimens were cured with steam of boiled water in a tank. The flexure test used three points loading method on a mortar prism of 40x40x160mm and compressive testing was on a broken part of prism with surface area of 40x40mm. The results showed that steam curing increased flexural strength of premixed mortar very sligtly and increased gradually the compressive strength in line with the ages. The addition of cement also increased gradually both flexural and compressive strength in line with the increase of cement adition. The requirement of compressive strength for ferrocement mortar was reached with 40% of cement addition in the premixed mortar. The use of admixtures had no effect on both flexural and compressive strength.
