通过对LC30轻骨料混凝土进行骨料预湿，选择搅拌工艺和复合掺合料，添加增粘剂等方法，探寻轻骨料混凝土的配制思路，试验发现，添加增粘剂并经预湿处理的全轻骨料混凝土，在能够满足强度等级要求和工作性的前提下，密度可降至1650 kg／m3。
通過對LC30輕骨料混凝土進行骨料預濕，選擇攪拌工藝和複閤摻閤料，添加增粘劑等方法，探尋輕骨料混凝土的配製思路，試驗髮現，添加增粘劑併經預濕處理的全輕骨料混凝土，在能夠滿足彊度等級要求和工作性的前提下，密度可降至1650 kg／m3。

According to some methods for LC30 light-weight aggregate including aggregate pre-wetting,selection of mixing craft and composite mixtures,addition thickening agent,the paper explores the preparation ideas for the light-weight aggregate,and finds from the tests that the total light-weight aggregate with addition of thickening agent and pre-wetting treatment can meet the strength grading requirements and its density can be lowered to 1 650 kg/m3 with the premise of workability.
