The blocks were manufactured with the use of manual method of moulding with 6‟‟ (450mm x 225mm x 150mm) mould. Two-mix ratios (1:6 and 1:8) cement-sand ratio were used, varying cement replacement with sawdust ash amounting to 0%, 5%, 10%, 15% and 20% were used. The …

Blocks of cement and sawdust are called arbolitovye. They have many advantages, chief among which are insulation and sound absorption. It is an eco-friendly, reliable and affordable option for the construction of low buildings and adjacent outbuildings.

A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment buildings.The slab has been especially popular in countries where the emphasis of home construction has been on precast concrete, including Northern Europe and former socialist countries of ...

the brick making machine has different molds and each mold can produce a different shape and size of a hollow block. brick making machine uses pressure and vibration to compress the mortar, so the produced hollow concrete blocks have better quality. The pressing force is usually 150 Bar and the vibration force is normally 36.500kg. this will result in compacted blocks with higher …

sawdust using a vibrating block moulding machine. Sandcrete hollow blocks without sawdust as aggregate were servedas a control.
