Sawdust was used to replace fine aggregates from 0% to 50% in steps of 10%. Concrete cubes measuring 150 x 150 x 150mm were cast and their compressive strengths evaluated at 7, 14, 21 and 28 days. ...
Sawdust is a by-product generated during the process of manufacturing. The recycling of such waste provides the benefits of reducing the need to extract new raw materials and limiting the air pollution due to incineration. The potential of bamboo sawdust as a replacement of fine aggregates in concrete hollow blocks. 2. BACKGROUND OF THE STUDY
OPC: Ordinary Portland cement, FA: F ine Aggregate, SDA: Sawdust Ash, LFA: Lignite Fly Ash, SP: ... The GW was introduced with 5%, 10%, and 15% replacement of fine aggregates, and CTW was ...
Normal concrete were made with different types of fine aggregate. The fine aggregate considered were sharp sand (control sample), sawdust, crushed groundnut shell, crushed palm kernel shell and ...
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 …
by replacing fine aggregate with sawdust b y 15%, 20%, 25% & 30% and to compare their property with standard mix (M25).Based on the investigation on sawdust, following conclu-
The use of sawdust by replacing fine aggregates can be helpful to the construction industries in terms of economic and environmental aspects. In the present study, …
The blocks were created by adding sawdust at a weight-replacement ratio of 5% to fine aggregates. The sawdust was treated using two different methods: one involved washing it in lime, an alkaline solution, and the other involved submerging it in aluminum sulfate. On day 28, the results for the two treatment methods' compressive strength were ...
partial replacement of the fine aggregate with sawdust. Furthermore, the results revealed that the as the sawdust volume increased from 0% to 5%, the compressive strength declined by 38%; while as ...
sawdust. Materials and methods Aggregates Fine aggregate from the "La Victoria" quarry, located in the Lambayeque Region, Peru, was used, which had a fineness modulus of 2.34. The coarse aggregate was used from the "Pacherres" quarry, located in the Lambayeque Region, Peru, which had a maximum grain size of 25.4 mm and a
on the effect of replacing fine aggregate with sawdust on the properties of concrete. A concrete mix of 1:1.5:3 is used while sawdust was used to replace 10%, 20%, 50% and of sand by volume. The percentage reduction in density is 4.02%, 5.54%, 9.15% and …
(Ugwu, 2019) made a full replacement with the sawdust in place of the fine aggregate in the production of lightweight aggregate in which resulted in a wider variation in …
The Performance of Bamboo Fiber as Fine Aggregate Replacement in Concrete. July 2021; ... Sawdust is compos ed of small chippings woods whi ch is known as the main co mponent in the particleboard ...
The results revealed that the compressive strength on the concrete decreased from 27.1 MPa to 9.4 MPa, as the sawdust volume increased from 0% to 12.5%. Similar results were obtained Ganiron (2014 ...
The aim of this study was to investigate the feasibility of utilizing sawdust in a concrete. The mix ratio adopted to prepare concrete is 1:1.5:3 with a water-to-cement ratio of 0.55 natural sand used as a fine aggregate in concrete and the same was partially replaced with sawdust at various percent of 2.5, 5.0, 7.5, 10, and 12.5%.
Abstract. This experimental study is aimed to create a concrete mixture consisting of sawdust which replaces the fine aggregate. It is also used to analyze the effect of sawdust concrete in terms ...
The paper examined the types of sawdust suitable as partial replacements of fine aggregate in concrete. Two different types of sawdust sourced from Afara and Doka wood species were used for the experiment. DoE Method was used to design and produce
Six sets of concrete were made by partially replacing the fine aggregates (sand) and coarse aggregates (gravel) with 0, 5, 10, 15, 20 and 25% of sawdust and periwinkle shells respectively, in the ...
This research supports green eco-friendly construction through utilization of laterite and sawdust ash as fine aggregate and supplementary cementitious material in concrete. Critical literature review revealed that at fine aggregate replacement by laterite ≤50, 50–75 and , mix ratios 1:2:4:0.56, 1:1.5:3:0.65 and 2:3:6:0.65 respectively ...

Saw dust Ash (SDA) generated from rice mills is usually delivered to landfills for disposal. Using of sawdust ash in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources .This paper examines the possibility of using sawdust ash as replacement in fine aggregate for a new concrete.
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. This …
sawdust for sand in dierent percentages, such as 5%, 10%, 15%, 20% and 25% by weight. The study examined that the more the amount of sawdust ratio by weight is replaced with ne aggregate, the more compressive strength decreases. Muhedin et al. (2020) experimented on sawdust as a partial replacement material for ne aggregate and investigated the
Similarly the fine aggregate is replaced with saw dust with percentages up to 15% at an interval of 5%.All these casted cubes and cylinders were cured for 7 and 28 days and are tested to find out the compressive strength and spilt tensile
