INVESTIGATING THE EFFECT OF DIFFERENT SAND TYPES ON DIFFERENT CEMENT

ABSTRACT

The construction industry relies on the synergy of various materials to create structures that are both resilient and dependable. Among these materials, sand and cement are crucial in shaping the properties of concrete, the fundamental building block of infrastructure. This research project focuses on discerning the impact of distinct sand types, specifically sharp sand and silt sand, on the performance of varying cement grades, namely Grade 42.5 and Grade 32.5, in concrete mixtures. The study adopts a comprehensive approach, combining laboratory experimentation with rigorous data analysis. Diverse concrete mixtures are meticulously crafted by systematically altering the sand types (sharp sand and silt sand) and cement grades (Grade 42.5 and Grade 32.5). The evaluation of these concrete mixtures revolves around critical parameters, including workability, compressive strength, and durability. Preliminary findings indicate that the choice of sand significantly influences concrete workability, with sharp sand generally enhancing workability in comparison to silt sand. Additionally, the selection of cement grade bears a notable impact on concrete compressive strength, with higher-grade cements generally yielding stronger concrete structures. Furthermore, the study delves into the durability of these concrete mixtures, examining their resilience in the face of environmental stressors such as chemical exposure and freeze-thaw cycles. Initial results illuminate variations in durability performance, underlining the intricate interplay between sand type and cement grade.
