Abstract

Concrete has the advantages of high compressive strength, resistance to fire and weather, concrete mixtures are easily transported and formed according to needs, and maintenance costs are quite low. The more developed concrete technology, the higher the concrete criteria will increase. The purpose of this research is to determine the effect and value of compressive strength produced by concrete with the addition of silica sand, fly ash, and superplasticizer to the compressive strength of the concrete. The variation of silica sand for the concrete used is 10%; 15%; 25%; 30%; For ingredients added fly ash using a percentage of 10% of the weight of cement, the percentage of superplasticizer 0.6% of cement. The specification of planning using concrete fas: 0.3. Each variation was made in 3 samples with a mixture of silica sand, fly ash, and superplasticizer for the manufacture of concrete cylinders with a concrete age of 28 days. The diameter of the concrete cylinder used is 15 cm with a height of 30 cm and the specimen beam is 53 cm long, 15 cm wide, and 15 cm high. Tests are carried out at the age of 28 days. Obtained the test results on average compressive strength with a mixture of silica sand, fly ash, and 10% superplasticizer; 15%; 25%; 30% is obtained at 29.251 N/mm2, 33.309 N/mm2, 33.403 N/mm2, 35.856 N/mm2. For the average flexural strength of the concrete beam the test results were obtained with a mixture of silica sand, fly ash, and 10% superplasticizer; 15%; 25%; 30% is obtained at 4.356 N/mm2, 4.933 N/mm2, 5.711 N/mm2, 6.044 N/mm2
