Treated Sea Sand (TSS) 25–100: Concrete with treated sea sand has a strength increase of 6.71% due to micro-organic matter and chloride removal. [15] Crumb Rubber (CR) 5–20: Treated rubber increased its compressive strength due to surface modification of fine aggregate, resulting in increased binding between rubber and cement paste. [16]
Findings of the study revealed that the concrete mixture using sawdust is comparable to the compressive strength of concrete mixture using sand as fine aggregate. Thus, the sawdust …
Insulation of walls with sawdust concrete is carried out using a heat-insulating type of material. Its density is no more than 400 kg / m3, but the thermal conductivity does not exceed 0.11 W * mC. That is why insulation with sawdust concrete is even more popular than the construction of walls using it. Furthermore, not just goods are utilized.
of concrete made of quarry rock dust is nearly 10% more than the conventional concrete.This Experimental study is an attempt to find the optimum usage of robosand and Saw dust in normal concrete by replacing the river sand by 0- in steps with 0 to 80% (20% increment) of ROBO sand and 0 to 20% (5% increment) of sawdust in combination.
This impact the performance of concrete as one of the reasons might be vibrator issues for consolidation process. Such type of situations needs a relaxation in terms of placing the concrete without or less vibration techniques. Self-Compacting Concrete (SCC), which flows and settles on its own under self-weight, could represent the solutions.

Advantages of Robo sand or m sand are : No or near zero impurities. Controlled gradation of particles. Hence, no wastage. No over sized particles or shingles, stones and pebbles. Generally dry, so doesn't fiddle with …
Exporter of Robo Sand, Concrete, Construction Sand offered by Moin Stone Works, Secunderabad, Telangana.
Advantages of manufactured sand are as follows; Reducing defects in concrete like segregation, bleeding and honeycomb structure formation.; Setting time of concrete is comparatively fast as compared to another type of concrete where we use natural sand; Compressive strength and flexural strength of concrete is very high as compared to other …
The study determined the strength of concrete mixture with sand and concrete mixture with sawdust in three different curing periods; 7 days, 16 days and 28 days. Experimental method was used by the researchers for it examined and investigated the possibility of using sawdust as a fine aggregate in concrete mixture with both mixtures categorized ...

Adebaku et al. [9] incorporated sawdust in hollow concrete sand blocks and proved that at 10% replacement sawdust with sand in mortar, the overall cost and weight can be reduced by 3% and 10% ...
This study explores the use of sawdust as a partial replacement for sand in creating M20-grade concrete cubes, as the depletion of good quality sand sources is observed globally.
The most common mixture used for walls consists of 3 parts sawdust, 2 parts sand and 1 part cement. For smaller panels, 4 parts sawdust is usually satisfactory. The sawdust should be from hardwood - which is low in tannin, gums and oils - for the best results. Most people mix the ingredients in a large, shallow metal tray using hoes or rakes.
Concrete with replacement of cement by fly ash (varying from 0 to 20%), of sand by sawdust (10 and 40%), PET (0 to 60%), or polystyrene (0 and 20%) (w/c = 0.5, Portland cement type II 42.5 R).
Gypsum-based sawdust concrete. Sawdust concrete can be made using a method that uses gypsum as a binder. Gypsum's primary benefit is its rapid drying time. Gypsum blocks harden five times faster than cement. It is necessary to add a detergent to the mixture in order to stop the plaster from setting right away after adding water.

The typical ingredients of sawdust concrete are wood shavings, lime (if needed), and a cement-sand mixture. The use of wood shavings, which strengthens monoblocks, is permitted. Prior to preparation, the dry mixture needs to be sifted through sieves measuring 20 x 20, 10 x 10, 5 x 5 mm, and 10 x 10 mm for shavings.
A batch of sawdust concrete consists of two 10-liter buckets of sand, one 10-liter bucket of cement and four 15-liter buckets of large sawdust. We pour these ingredients into a concrete mixer and mix thoroughly, sometimes helping with a shovel when the unit is turned off. Lastly, add 10 liters of water without stopping the stirring process.
