Abstrac This research was conducted to determine the effect of the addition of waste shells and shell powder glass powder on the compressive strength of concrete. The method used is to use the experimental method by making test specimens with a mixture of waste shells powder shells and glass powder by 4%; 8%; 12% then compared with normal concrete without added ingredients. Concrete specimens that have been soaked then tested their compressive strength with the age of 7 days, 14 days, 21 days, and 28 days. The results of the test showed that normal concrete which was not added with the waste of shell powder and glass powder had compressive strength under mixed concrete variations of 4%, 8%, and 12 % when the concrete was 28 days old. Concrete which is added with waste of shell powder and glass powder has  a high yield at 4% variation that is equal to 20,66 MPa. For concrete Variasi of 8% has a compressive streng value of 20,17 MPa, For variations of 12% has a compressive strength value of 20,46 MPa and for normal concrete has a compressive strength of 20,16 MPa at the age 28 days. The compressive strength value generated by the research that occurs due to the slump test value factor that is done is not the same.                       Keywords: Concrete, scallop waste powder, Glass powder waste, concrete compressive strength.

Compressive Strength Of Concrete

Abstract As a material of construction, concrete have a good compressive strength but low tensile strength. From the previous study, reducing the tensile weakness of the concrete using empty fruit bunch (EFB) of Palm for the concrete mix have a significant result. But in contrary, the use of this fiber decreases the compressive strength of concrete. This research aims to optimize a mixture of glass powders on EFB fiber as a solution to increase the compressive and tensile in strength of concrete as well. The fiber material requires pre condition treatment which is soaked in 10% NaOH for 6-10 hours, then is followed with drying for 24 hours and finally cutting into 4 cm pieces long. Using glass powder as mix design with fiber material which is substitute for fine aggregate in concrete. Variation of 0.25%, 0.5%, 0.75%, 1%, 1,25%, 1,5%, 1,75%, and 2% fiber material mix up with 10% glass powder used for concrete specimens with a diameter of 15 cm and a height of 30 cm at the age of 28 days testing. The results of this study shows an increase in the compressive and tensile strength of concrete compare to normal concrete. The optimum compressive increase 21.02% of normal concrete which is 24.87 MPa. Meanwhile the tensile strength an increase of 31,78% of normal concrete which is 3,11 MPa using 1% fibre and 10% of glass powder. Hence, using glass powder mix in EFB to increase compressive and tensile strength of concrete can be developed optimally in the future.

Bagasse ash is a waste from the sugar factory industry which has silica content and grain size is relatively the same as cement. Glass powder is made from industrial glass and household waste, has a silica content and grain size is relatively same as sand. The use of both wastes as concrete substitutes is expected to reduce environmental pollution and exploitation of natural resources. This study aims to determine the effect of bagasse ash as a cement substitution and glass powder as sand substitution in a concrete mixture on the compressive strength. This study uses a mixture of bagasse ash 2.5%, 5%, and 7.5% by weight of cement, and the glass powder is 5%, 10%, and 15% by weight of sand. Compressive strength testing on days 7 and 28. The results of this study are the higher percentage of substitution materials, workability will decrease. Compressive strength testing shows that all variations have resulted under normal concrete. The highest compressive strength is obtained from variation A with a mixture of 2.5% bagasse ash + 5% glass powder that is 24.50 MPa. Variation of the mixture with bagasse ash of 2.5% has a higher compressive strength than other variations on day 28.
