sawdust is added the coefficient decrease against the reference concrete SD0 and the concrete with addition of sawdust is a very good material for thermal insulation. 6. The best percentage of sawdust used to substitute fine aggregates in composition of the concrete, considering all the tests made, is 20%. This has a better compressive strength,

the fine aggregate. It is also used to analyze the effect of sawdust concrete in terms of workability, adhesion of aggregates and etc. After preparing the concrete block, the difference in weight between the original concrete and the sawdust concrete block is also tested. The sawdust is mixed in definite proportions with the concrete.
structural characteristics of sawdust-sand-cement composite which is a concrete mixture of sawdust, cement and sand. The ma- terials used in the laboratory experiments include: Ordinary Portland Cement, river sand, sawdust, and water.

The utilization of recycled aggregate is particularly very promising as 75 per cent of concrete is made of aggregates. In that case, the aggregates considered are slag, power plant wastes, recycled concrete, mining and quarrying wastes, waste glass, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.
The use of sawdust for making lightweight concrete has received some attention over the past years (Udoeyo and Dashibil, 2002). Mageswari and Vidivelli (2009) reported, that as a substitution material for natural sand, sawdust ash might be the right choice as fine aggregate in concrete. It can considerably reduce the dumping problem and ...
Sawdust As Fine Aggregates. Sawdust can be used as alternative substitute for fine aggregate in concrete production 8 10 sawdust should be washed and cleaned before use as concrete constituent because of large amount of bark which can affect setting and hydration of cement concrete obtained from sawdust is a mixture of sawdust gravel with certain.
at 10% sawdust replacement, production costs and weight reduced by 3% and 10% respectively. Usman et al (2012) found out that the strength of concrete reduced with sawdust as fine aggregate due to its higher rate of water absorption and the optimum replacement was 25%. Olutoge (2010) investigated the suitability of palm kernel shells and 1349 ...

flexural strength. Natural Fine Aggregates are replaced by Sawdust in 5%, 10%, 15%, 20%, 25% and 30% by weight in the concrete. Fly Ash and coir are kept constant at 20% and 4% respectively to the weight of the cement throughout the mix. Fly Ash presents good pozzolonic properties, Sawdust shares similar properties as Natural
The compressive strength increases from T 1 (24.253 MPa) to T 4 (29.127 MPa) and decreased abruptly as the amount of fine sawdust increases from T 4 (29.127 MPa) to T 6 (10.123 MPa). The observed increasing strength could be due to the presence of fine sawdust acting probably as filler material.
Abstract. This experimental study aimed to develop an acceptable concrete mixture with sawdust particles as substitute to fine aggregate that can be used for building construction particularly in residential class concrete slab and analyze the effect of sawdust concrete mixture in terms of adhesion of aggregates, thermal insulation, workability and surface quality.
One of the areas to be explored is the enhancement of the strength and durability of PC by adding fine sawdust as low-cost internal curing agent (Usman et al., 2018), filler material and/or as additive in lieu of fine sand (Belhadja et al., 2014). Water absorbed by sawdust (or wood aggregates in general) when it is mixed with other concrete ...
