- In this work, the strength, water tightness and average density of modified expanded clay lightweight on different types of sands were investigated. Quartz sand, expanded clay sand and sand from granulated foam glass were used. It is shown that structural lightweight expanded clay concrete on light sand from granular foam glass is effective for thin-walled structures of hydraulic structures, if necessary, to reduce their weight. It was established that the average density of lightweight expanded clay concrete on a mixture of quartz sand and granulated foam glass is 1400-1440 kg/m3, water tightness is W10-W12, compressive strength up to 21 MPa, tensile strength in bending up to 5 MPa. Interstitial partitions of foam glass have an amorphous vitreous structure. The lightweight expanded clay concrete with sand of granulated foam glass has a high-water resistance and sufficient strength for thin-walled structures.
