Review of Related Literature # 4 Hollow and dense cement concrete blocks, also known as hollow blocks, have been developed as an alternative to bricks. It is widely use product in construction activity. Hollow blocks are made of cement, stone chips, stone dust and sand. It's not only cheaper than the bricks but have other…

In this study, walls made of two different types of blocks were studied, such as: "lime sludge" (MSLM) and "sawdust" (MS), respectively, whose results were compared to those blocks made by the traditional concrete (MREF), showing great decreases of the U-values up to 10.5% for the case of the MS.

Production of sandcrete blocks were made by partial replacement of sand with a varying proportion (10%, 20%, 30% and 40%) of sawdust. The strength of each block was determined to ascertain conformity with the minimum acceptable standards. Equally, the weights were checked and compared with blocks devoid of sawdust.

In this study, use of glass powder and marble powder as partial replacement of cement in various proportions (5%, 10%, and 15% by weight) in manufacturing of non-load bearing hollow concrete blocks is investigated. The manufactured blocks were evaluated for various characteristics as per ASTM C140/C140M, such as compressive strength, dry density and water absorption. Marble …

This study investigates the use of Saw Dust Ash (SDA) as partial replacement for ordinary Portland cement (OPC) in sandcrete blocks. Some units of sandcrete hollow blocks were produced by partially replacing the cement content with 5% to 25% by weight of SDA, using vibrating block moulding machine. Sandcrete blocks without SDA serve as the control.
