采用混合型集料 ,以堆积密度690kg/m3 ,筒压强度4.32MPa的粘土陶粒 ,研制出密度等级为1800 ,抗压强度为40～50MPa的轻集料混凝土。该混凝土收缩小 ,吸水率低 ,软化系数94.85 % ,经50次冻融循环无损 ,耐海水侵蚀 ,与钢筋粘结力强 ,可广泛应用于船舶、涵洞、隧道、海港、桥梁及钻井平台等海洋工程 ,更适用各种轻质高强的工业与民用建筑结构混凝土工程。 A mixed aggregate was used to prepare lightweight aggregate concrete with a density of 1800 and a compressive strength of 40-50 MPa with a clay density of 690 kg / m3 and a barrel pressure of 4.32 MPa. The concrete has small shrinkage, low water absorption, 94.85% softening coefficient, no damage after 50 freeze-thaw cycles, corrosion resistance to seawater and strong adhesion with steel bar, which can be widely used in ships, culverts, tunnels, seaports, bridges and drilling platforms. Marine engineering, but also for a variety of light and high strength industrial and civil construction concrete structure.
