Abstract
Gaza Strip suffers from a real problem in the sources of energy needed while a heavy use of electric power has become essential for Air conditioning purposes and comfort inside buildings where outdoor temperatures fluctuate in summer and winter. The use of insulating materials is not popular in Palestine, in spite of their long-term financial benefit, due to the fact that installation of such materials is expensive and requires skilled labor so the development of simply handled mortar blocks with high thermal insulation properties becomes a necessity. The present paper aims to evaluate the thermal and physical properties,namely, thermal conductivity, density, morphology and mechanical strength of foam mortar which used to manufacture a Lightweight Blocks. Six different mortar mixes were produced, Cocamidopropyl Betaine (CB) used as an air entraining agent. Morphology, compressive strength, as well as density, were determined for 28 days samples, thermal conductivity is also determined after 28 days. The results show that as the air content increase the compressive strength, density, and thermal conductivity decreases,and reach its maximum at 8% (CB) with a thermal conductivity lower from 0.76 to 0.12 W/ m.k. The SEM Analysis shows that the addition of (CB) produces consistent bubble structure with a uniform and homogenous bubble structure. Building blocks with performance improved in these ways will be beneficial for developing low-cost insulation building for local people.
