Abstract
Liquid membrane-forming compound curing is a type of water retaining curing concrete technique by forming a membrane on the surface of the concrete. This study aimed to investigate the effectiveness of liquid membrane – forming concrete curing compounds produced in Ethiopia. The methodology include compressive strength and water absorption (on C-25 and C-40 grades of concrete) for samples examined under laboratory conditions and by exposing samples to external weather conditions which were cured through curing compounds, water sprinkling and plastic sheet covering. Additionally drying time and deleterious reaction tests were carried out. Liquid membrane – forming concrete curing compounds produced in Ethiopia are effective in compressive strength but not in water absorption, which water absorption was used to measure concrete quality in this study. Water sprinkling and plastic sheet covering methods were effective in compressive strength and water absorption than curing compounds. Regarding cost comparisons, water sprinkling method of curing is less costly than curing compounds and burlap coverings, and curing compound is more costly than the two.
