AN ANALYSIS OF RAW MATERIALS FOR CONCRETES AS METAL SHEETS FOR SOLAR RADIATION ABSORBER

N.R. Ismail, N. Fuhaid

Abstract: Various researches have been made in terms of materials for absorping heat and their usages. Previous researches have not started from testing the basic materials for cast concrete, therefore it is necessary to investigate the materials as heat absorbers from the solar radiation. In this present research, an experimental method was employed to test the basic materials for cast concrete (cement, fine and har aggregates). This study is intended to know the specific weight, cement quality, heat-affordability treatment , and test for solar radiation-heat absorption and storage. From the research results, it can be concluded that dealing with materials, the best type of sand is that of iron sand and the the best cast stone is that of hulled cast stone. From the specific weight, heat-affordability treatment, and solar radiation-heat absorbsion and storage, the type or trademark of the best cement is that of Puger-Jmeber. It is also the case for the mortar-pressure power, heat affordability treatment, and solar radiation-heat absorption and storage.

Keywords: sand, cast stone, cement, specific weight, heat affordability, solar radiation.
