Lightweight blockwork density
WebThe main specialties of lightweight concrete are its low density and thermal conductivity. Its advantages are that there is a reduction of dead load, faster building rates in construction and lower haulage and handling costs. Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall. WebThe strengths of the units were 25.7 MPa for a frogged calcium silicate brick and 13.0 MPa for a dense aggregate solid concrete block, while the strengths of the cement–lime …

WebThe lightweight concrete blocks can help reduce heavy lifting and carrying by minimizing the weight of the concrete blocks that must be lifted and carried during brick-laying tasks. … WebProduced in greater volume, but less strong than dense blocks, lightweight blocks are used in both internal and external walls where loading is slightly more restricted or as infill blocks in beam and block flooring. Their main advantage over dense aggregate blocks comes from a combination of higher insulating properties and a lighter unit weight.
