| description | Thermal insulation is one of the main problems facing the engineers working in building and housing sector spatially for the high summer temperature in the most Arab Gulf and spatially in Iraq, so the study of lightweight aggregate thermal insulation (No fine concrete) is important. The experimental work consist of concrete mixes (cement: porcelinite aggregate) ratios (1:4), (1:5) and (1:6) and for each mixes cement content changes (200, 300 and 400) Kg/m3. Dependence on mixing (1:5) and cement content (300Kg/m3) change the water to cement ratio (0.4, 0.45 and 0.5) by weight. The research presents the tests of density, absorption, porosity, ultrasonic pulse velocity, accelerated compressive strength according to British standard (BS 1881: Part 112: 1983), normal compressive strength at 7, 28 and 90-day. Light weight concrete was obtained of density ranging from (721-770) kg/m3 and thermal conductivity ranging from (0.17- 0.24) W/ (m.K). The good correlation between accelerated compressive strength at one day with normal compressive strength at 28- day is approximately (0.245 ±0.005) for water bath at 55°C and (0.335±0.05) for water bath at 82°C. |
