EFFECT OF REPLACEMENT OF FINE AND COARSE AGGREGATE BY SAWDUST IN SOLID CONCRETE BLOCKS FOR DIFFERENT MIX PROPORTIONS 1Owais Ahmad Lone, 2Anaab Saleem, 3Isha Chandra 1M.Tech Student, 2B.Tech Student, 3Assistant Professor 1Civil Engineering, 1NIU, Greater Noida, India Abstract:
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
The study was an experimental study on hollow concrete blocks in a partial replacement of fine aggregate with sawdust in different proportion. The amount and kind of cement was constant, but the quantity of sawdust, aggregate and water was varied. The study was conducted in different steps
sandcrete blocks were produced in percentage by weighting the fine aggregate and sawdust as partial replacement in fine aggregate for sandcrete blocks in 5%, 10%, 15%, and 20% respectively. Ranging from 0% to 20% replacement for fine aggregate and saw dust. The specimens were made in accordance with Nigeria Building codespecifications
sand used concrete block and sawdust used concrete block. For making the concrete blocks we are using coarse aggregate, fine aggregate, cement, water and sawdust to mix it. Using some percentage of sawdust in place of sand in concrete is used. We replace replaces 10%, 15% and 20% of sawdust instead of sand while other things are same. After
May 05, 2020 vibrocompression by replacing part of the fine aggregate with sawdust. The physical properties of concrete block, such as compression strength and thermal conductivity were studied. Gopinath et al [7] studied the physical properties of concrete by replacing part of the fine aggregate with sawdust and replacing part of cement with sawdust ash

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
Table of content for a project work on sawdust in partial replacement of fine aggregate in concrete production Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Table of content for a project work on sawdust in partial replacement of fine aggregate in concrete production
2.2.Fine aggregate The fine aggregate used was locally available river sand and wood waste and conforming to IS: 383 – 1970. The fine aggregate was tested for its physical requirements such as gradation, fineness modulus, specific gravity and bulk density. A concrete can be made from sand consisting of rounded grains as
and autoclave blocks. Use of quarry dust as fine aggregate in concrete draws serious attention of researchers and investigators. Cement bricks are conventionally produced by using cement and fine aggregates in 1:6 mix these bricks also be produced by using wastes generated by stone crushers, quarry and saw dust from wood industry. Two
Construction Materials and Testing 2018 other practical uses, including serving as much, as an alternative to clay cat litter, or as a fuel. Sawdust can be used as alternative substitute for fine aggregate in concrete production. Before using the saw dust it should be washed and cleaned because of large amount of barks are present which can affect setting time and heat of hydration of cement
Investigation on Sawdust and Palm Kernel Shells as Aggregate Replacement”. In this project he subjected the use of sawdust and palm kernel shells (PKS) as replacement for fine and coarse aggregate in reinforced concrete slabs. Increase in percentage of sawdust or palm kernel shells in concrete slabs lead to a corresponding
This paper focuses at the replacement effects on the addition of Fly Ash, Sawdust and Coir in concrete as a partial replacement of Cement and Natural Fine Aggregates, respectively. Coir, here acts
The only downside to using sawdust as fine aggregate in concrete mixes is its weakness which is water. Experimentation and data analysis shows that the higher the saturation of water deposits in the sawdust particles during curing tend to weaken the sample, making it softer than it was designed for, thus explaining why the soaked and splashed sample appeared weak

Effect of Sawdust as Fine Aggregate in Concrete Mixture for Building Construction. 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
Fine aggregate = 1.3 5.7664 = 7.495 kg Saw dust = 1.3 201.2 = 261 gm Density Standard concrete density:- Mass of concrete = 8.43 kg Size of concrete block = 15cm 15cm 15cm Volume of concrete = 3375 cm Density = mass volume = 2497.77 kg/m 20% replacement of fine aggregate:- Mass of concrete = 7.938 kg
This experimental study aimed to develop an acceptable concrete mixture with sawdust particles as a substitute to fine aggregate that can be used for building construction particularly in the
The compressive strength of concrete blocks units decreased due to the effect of sawdust waste and wood waste aggregate by increasing the replacement ratio instead of cement, sand and coarse
and private developers. This study investigated the use of sawdust as partial replacement for fine aggregates in concrete production. 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. Increase in percentage of sawdust in concrete cubes
Partially replaced sawdust with sand in proportion used as fine aggregates in concrete and Today we are using river bed sand in construction projects all the compressive and split tensile strength were tested
