Study the Properties of Mae-Khong Alluvial Gravel Concrete for Producing the Non-Bearing Thin Wall Concrete

Abstract:

This work studies the development of using the Mae-Khong Flat Shape Alluvial Gravel which mostly found in Mae-Khong River as the raw material of the concrete combinations (GVCM) to produce the non-bearing thin wall. There are three main material properties investigated: the compressive strength, the tensile strength and the thermal conductivity. All properties are also compared with limestone concrete (LSC) which is widely used in normal concrete works. Results show that all properties of both materials increase with increasing cured time. For GVMC, the compressive strength increases as 6.66% for cured time from 28 to 180 days. The ratio of compressive strength to tensile strength is 8.69 compared with LSC which the value is 8.89. These can confirm that GVCM has the enough quality to produce the non-bearing materials according to the Thai community product standard.
