| Abstract | This research aimed to produce a type of lightweight concrete aggregate by using available local materials. The lightweight aggregates were produced using methods of sintered strand produced from Iraqi Attapulgite. Clay particle size, firing temperature, and firing soaking time were selected to determine the effectiveness of these parameters on the relative density of produced aggregate. It was found that decreasing particle size has a negative effect, and the optimum firing temperature is 1100ฐC for 30 minutes. The unit weight density for LWA obtained is about 808 kg/m3 , and the relative density is 1.445. |
