Abstract

Reinforced concrete is a combination of concrete and steel, where reinforcing steel provides tensile strength that concrete does not possess. Wlingi sand is sand that has a high level of silica. The function of silica to functional extender adds durability and anti-corrosion and anti-weathering properties. The purpose of this study is to find out the strong press, strong pull wire mesh, cracks, cracks, and faults and to find out if the test results can qualify as concrete plates—testing on test objects by the required SNI. The results showed that the compressive strength test value got an average value (28.38 Mpa), the wiremesh tensile strength test had average yield stress (393.42 Mpa), and tensile stress (569.30), and the seepage test were obtained the mean value (0.45%). The test for cracks and fractures obtained an average (1.72 Mpa) (2.18 Mpa). Test results showed wire mesh steel could be used as a concrete plate reinforcing because it has tensile voltage and melt voltage exceeding the minimum allowable limit of 390 Mpa and 240 Mpa.Beton bertulang adalah kombinasi antara beton dan baja, dimana baja tulangan memberikan kekuatan tarik yang tidak dimiliki beton. Pasir wlingi merupakan pasir yang memiliki kadar silika yang cukup tinggi, fungsi dari silika untuk ekstender fungsional menambah daya tahan dan sifat anti korosi serta anti pelapukan.Tujuan dari penelitian ini adalah untuk mengetahui kuat tekan, kuat tarik wiremesh, rembesan, retakan dan patahan dan untuk mengetahui apakah hasil pengujian dapat memenuhi syarat sebagai pelat beton.

Abstract

Concrete is a material that is widely used in the construction sector. The use of sustainable concrete constituent materials will result in the depletion of these materials. That is a need for innovation in the use of concrete materials. Husk ash and straw ash contain silica contained in cement material. Further research is needed on the use of these materials. This research was conducted to determine the optimum compressive strength, moisture content, and concrete density of a mixture of husk ash and straw ash in concrete k-225 (Fc '18.68 Mpa) with variations of 0%, 5%, 10%, and 15% of weight cement. The specimens used are 15x30cm cylindrical and the test is carried out at 28 days of concrete. The results showed that the optimum compressive strength value was obtained in the addition of 5% with a compressive strength value of fc'22.5 MPa. The least water content value is in the addition of 10% with a value of 0.033kg. The specific gravity test results show that the value of specific gravity has decreased for each variation. So it can be concluded that the addition of husk ash and straw ash to the concrete mixture affects the compressive strength value.
