Abstract

Clay in nature consist of a mixture of grains and minerals with or without the content of organic matter. The variation in the size of clay grains and the proportion of their distribution is a very useful indicator for knowing soil behavior. Testing the combination of fine sand - clay (FSC) using clay from Kulim Pekanbaru and fine sand from Teratak Buluh Riau. Variants of the percentage of FSC are carried out with the types of tests carried out are Standard Proctor Test, Unconfined Compressive strength test, Direct Shear Test and sieve analysis test and hydrometer. Increasing the percentage of clay in the FSC variant, increases the liquid limit, increasses the plastic limit and increases the plasticity index. Increases optimum moisture content, decreases maximum dry density and increases soil friction angle and decreases compressive strength

Abstract

This study aims to utilize extracted Spent Bleaching Earth (SBE) waste as an additive material in the production of clay bricks. SBE waste is a by-product of the palm oil bleaching process, which is abundantly available and has the potential to cause environmental pollution if not properly managed. The variations of SBE content used in this research were 0%, 30%, 40%, 50%, and 60% of the total clay weight. Tests were conducted on the physical appearance, dimensions, porosity, and compressive strength of the resulting bricks. The results showed that the addition of SBE waste affected the color and surface texture of the bricks, where higher SBE content tended to decrease visual quality. The volume shrinkage values ranged from 35.24% to 39.34%, which still met the requirements of SNI 15-2094-2000. However, the compressive strength test results indicated a decrease as the SBE percentage increased, with the highest value of 2.70 MPa and the lowest of 1.76 MPa, both below the minimum SNI standard of 5 MPa (Class III). Overall, SBE waste can be utilized up to a 30% variation as an alternative additive material in brick production, but further optimization is required by reducing the mixture variation to meet the structural strength standards.
