The aim of this study was to shows the behavior of sawdust concrete at elevated temperature. Sawdust is considered as waste material but nowadays this waste material is utilized in the construction of the building as sawdust concrete. Sawdust is a by-product of wood which is generally used in the production of lightweight concrete, possessing low thermal conductivity.

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.

concrete cubes of size 150mm x 150mm x 150mm with different percentages by weight of corn cob ash and Saw dust ash to Portland cement in the order of 0%, 10% and 15% were cast. The concrete cubes were tested at the ages of 7, 14, 21, 28 and 56 days. The results showed that the corn cob ash and saw dust ash are a good pozzolans.

Compressive Strength of Concrete Using Sawdust as Aggregate Daniel Yaw Osei, Emmanuel Nana Jackson Abstract—This paper reports on experimental investigations on the effect of replacing sand with sawdust on the properties of concrete. A concrete mix of 1:2:4 was used as control while sawdust was used to replace 25%, 50%, 75% and of sand ...

It is envisaged that the reviewed literature will serve as a cata-lyst for more research on sawdust composites and for promoting increased utili-sation of these composites in construction. This would further contribute to the development of ...

Utilization of Sawdust in Concrete Masonry Blocks: A Review SAJJAD ALI MANGI*, NORWATI BINTI JAMALUDDIN*, ZUHAIB SIDDIQUI*, SHEERAZ AHMED MEMON**, AND MOHD HAZIMAN BIN WAN IBRAHIM* RECEIVED ON 12.10.2017 ACCEPTED ON 17.08.2018 ABSTRACT SDC (Sawdust Concrete) was developed in 19th century. It has been well recognized due to its lightweight

These composites include particleboards, sawdust concrete blocks or bricks and sawdust concrete. The article concludes that partially replacing 5% to 17% of sand with sawdust, or replacing cement with sawdust ash in proportions of 5% to 15% in concrete mixes can produce structural concrete with compressive strengths greater than 20 MPa.

Lightweight concrete is a type of concrete whose density is lower than the normal concrete. These lightweight blocks came into use mainly to reduce the dead weight of the structure and to reduce the cost due to use of heavy materials in construction. This project deals with the development of lightweight blocks by using EPS beads.

Dust and debris resulting from the sawing or cutting of concrete masonry units, blocks, bricks, tiles and other masonry products is collected via a three point dust and debris collection system.

Concrete cutting and concrete grinding are very dusty jobs in the construction industry, both posing a serious health risk to masons. Masonry blocks, bricks, and concrete slabs contain concentrated amounts of crystalline silica. When these materials are dry-cut they release silica containing dust into the workers' breathing zone. Regular exposure to this hazardous dust can
