Analisis Penggunaan Pasir Kuarsa dengan Tambahan Superplasticizer terhadap Kapasitas Kuat Tekan dan Tarik Belah Beton

The large number of concrete uses in construction has resulted in an increase in the
need for concrete materials. Aggregate is one of the materials that forms concrete that has the
largest composition, and quartz sand can be one of the additional aggregates in the concrete
mixture. This study aims to determine the effect of quartz sand substitution and superplasticizer
on the compressive and tensile strength of concrete. The results showed that the comparison of
each mixture of pure sand substitution with quartz sand added to the superplasticizer additive in
concrete could increase the compressive strength of concrete but the yield of tensile strength
decreased.
