Flooring Blocks for Drying Agricultural Products by using Quarry Rock as Aggregate with Coarse Bagasse Ash Partially Replace Quarry Rock and Fine Bagasse Ash Partially Replace Cement

Abstract

Currently, quarry rock and bagasse ash are waste materials in many industrial factories that need to be added to add value. The objective of this research is to study the use of quarry rock as a replacement for all sand in concrete production. The coarse bagasse ash partially replaced some of the quarry rock, and fine bagasse ash partially replaced cement. The ratio of hydraulic cement ingredients: fine bagasse ash (size passes through sieve number 325): coarse bagasse ash (size through sieve number 8 and remaining through sieve number 325): quarry rock equal to 1: 0: 0: 5, 0.85: 0.15: 0.05: 4.95, 0.85: 0.15: 0.10: 4.90, 0.85: 0.15: 0.15: 4.85, 0.85: 0.15: 0.20: 4.80, and 0.85: 0.15: 0.25: 4.75 by weight, respectively. The water: cement ratio (w/c) was kept at 0.4 by weight. There are two types of floor block compactor: 30 x 30 x 5 centimeters, properties tested according to TIS 378-2531 standards regarding concrete floor tiles and a crooked dagger-shaped floor paving block, size 11.5 x 22.5 x 6 centimeters, properties tested according to TIS 827-2565 standards regarding interlocking concrete floor paving blocks. The results showed that the compressive strength increased when coarse bagasse ash was used instead of quarry rock while bending strength and density tended to decrease. For water absorption, there is a tendency to increase. Concrete floor tiles mixed with bagasse ash at a ratio of 0.85: 0.15: 0.25: 4.75 and interlocking concrete blocks for floors mixed with bagasse ash with a ratio of 0.85: 0.15: 0.20: 4.80 provided the highest amount of bagasse ash. The flooring blocks still meet the required standard criteria. When used to dry agricultural products, fine bagasse ash should be used to replace only part of the cement.
