Abstract

Utilization of aqua fraction powder is a new alternative to obtain fiber concrete obtained from drinking bottle waste. The results of the waste are expected to increase and improve the mechanical and physical properties of concrete which are much better than concrete without added materials. The purpose of this research is to examine the effect and the optimum level of addition of aqua shard powder on the maximum compressive strength of concrete and assessing the feasibility of using aqua powder to estimate the level of ease in working concrete seen from the slump value. The research method applied is an experimental method involving 12 samples of cylindrical specimens with a diameter of 15 cm and a height of 30 cm. The variations of the aqua fractional powder samples used were 0%, 5%, 10% and 15% for 3 samples each. Based on the slump test, it was found that the slump value obtained every time the casting in each mixture corresponds to the specified slump value, which is 60-100 mm. Any mixture with and without aqua shard powder can be applied because it has good workability. Based on the results obtained, it can be concluded that the aqua shard powder can be used to make environmentally friendly concrete or a partial substitute for fine aggregate. In order to make maximum environmentally friendly concrete, it is recommended that fine aggregate be mixed with 5% aqua fraction powder.Keywords: aqua fraction powder, compressive strength of concrete, environmentally                  friendly concrete, slump value
