Pengaruh Penggunaan Zeolit Sebagai Bahan Pengganti Sebagian Semen Terhadap Kuat Tekan Paving Block Konvensional

Abstract

This research was motivated by the contained SiO2 in zeolite. The purpose of this research was to know the zeolite effect as a substitute of cement in constructing 14 days paving block material which used conventional method toward the compressive strength of paving block. This research used SNI 03-06-1996 in constructing and testing the materials. The material was cube shaped with ±5 cm size which consists of normal paving block and 6 variations with 5 specimens of each variation. Total of specimen were 35. Substitute of zeolite variations used 2,5%, 5%, 7,5%, 10%, 12,5%, and 15% on the weight of cement. The result of compressive strength of normal paving block is 15,64 MPa. The result of compressive strength test had increased in the variation of 2,5% zeolite substitute by 6,28% normal paving block. The result of compressive strength test results showed the greatest decrease in variation of 15% zeolite replacement by 39,05% against normal paving block.

Adsorpsi Uranium Terlarut Oleh Komposit Ammonium Dihydrogen Phosphate/Zeolit

“…Aplikasi zeolit, baik alami maupun yang dimodifikasi, telah banyak dimanfaatkan di berbagai bidang baik sebagai adsorben [10], katalis [11], pengering [12], penukar ion [13], [14] dan bahan bangunan [15]. Pemanfaatan zeolit sebagai adsorben banyak digunakan untuk menghilangkan senyawa organik dan logam berat dari limbah industri.…”

Utilization Of Pahae Natural Zeolite In The Production Of Polymer Concrete Using Corn Shell Fiber And Polyurethane Resin As Adhesive

“…In research conducted research by utilizing zeolite as a partial replacement for cement and had a good influence in making paving blocks because it was able to improve the quality of paving blocks with compressive strength parameters getting an optimum value of 15.64 MPa and water absorption so that it could effectively be used as a substitute for cement which was relatively expensive in production costs [9].…”
