| dc.description.abstract | Sawdust was used in place of fine sand in the 1:1.5:3 concrete mix ratio, which was created
using a water/cement ratio of 0.65 and sand replaced by sawdust of 0%, 25%, 50%,75% and
100%. The purpose of this experimental study was to create a workable concrete mixture that
could be used in place of fine aggregate in building construction, specifically for residential
class concrete slabs. It also aimed to examine the impact of sawdust concrete mixture on
aggregate adhesion, surface quality. In order to help the industry save the environment and to
give contractors new information, this also aims to identify the factors affecting the sawdust
concrete mixture's performance in terms of humidity and temperature. It also aims to design a
sawdust concrete mixture as an alternative fine aggregate for residential class concrete slabs
that will meet the requirements of the American Society for Testing and Materials (ASTM).The
compressive strength of concrete made with 0%, 25%, 50%, 75% and 100% sawdust after 21
days of curing are 15.77MPa, 10.71MPa, 2.70MPa, No strength gained, No strength gained.
The compressive strength of concrete made with 0%, 25%, 50%, 75% and 100% sawdust after
28days of curing are 16.57MPa, 11.28MPa, 4.58MPa, No strength gained, No strength gained.
The compressive strength of concrete made with 25% replacement of sand by sawdust shows
good strength behavior among the four mix designs. | en_US |
