Pengaruh Penambahan Jerami Dan Additive Beton Mix Terhadap Kuat Tekan Dan Lentur Beton

Abstract

The purpose of this study is to determine the properties collected from Botto Village of Sidenreng Rappang Regency in a uniform and comprehensive manner and to determine the relative strength and relative durability of concrete made using rice waste and additives using these materials. It is a complement to the practical study. The tests were carried out after 7 years of treatment, 14 days and 28 days, using 15 x 30 cm long cylindrical test tubes. It used 9 cylindrical and 2 jet models, each showing 5% and 10% difference. %. 9 cylindrical and 2 block tests were carried out for normal concrete, and 33 parameters were measured in these tests. According to the test results, the compressive strength of the concrete after 7 years with the addition of 5% grass and concrete mixture is 5.94 Mpa. and the total of 10% grass and concrete mixture is 7.83 Mpa. 14 years plus 5% grass and concrete mixture, this is 9. 06 Mpa for 10% grass and concrete mix 8.28 years plus 10.57 Mpa for 5% grass and concrete mix and 9.81 Mpa for 10% grass and concrete mix.

Key words: straw, compressive strength, concrete mix, flexural strength
