Effect of Sand Proportion on Fineness Modulus of Combined Aggregate, Workability, and Compressive Strength of Concrete
Aggregate is the largest proportion of concrete so it has a major effect on the properties of concrete. Aggregates consist of combined fine aggregates and coarse aggregates. Deficiency or excess of fine aggregate affects the fresh concrete and hardened concrete. The proportions of sand by weight used in this study are: 30%, 35%, 40%, 43.5%, 45%, 50%, 55%, 60%, 65%, and 70%. The water cement ratio is fixed at 0.52. Each variation consists of 3 concrete cylinders, with a total of 30 cylinders. From the research obtained, the increasing proportion of sand causes a decrease the fineness modulus of combined aggregate and workability. Increasing the proportion of sand to a certain extent from the results of the mix design increases the compressive strength. The proportion of sand less and more than results of the mix design decreases the unit weight.
