Abstract
Penelitian ini bertujuan mengetahui nilai kuat tekan maksimum beton speedcrete dengan menggunakan bahan tambah additive naphthalene pada tiap umur pengujian dan membandingkan dengan beton normal umur 28 hari. Penelitian ini dilaksanakan di Laboratorium beton PT. Torsina Redikon Pulogadung dengan metode eskperimen. Penelitian ini menggunakan benda uji berbentuk silinder dengan diameter 15 cm dan tinggi 30 cm. Beton speedcrete tidak mengalami proses perawatan sedangkan benda uji beton normal melalui proses perawatan. Pengujian kuat tekan beton speedcrete menggunakan alat Crushing Test Machine. Dalam penelitian ini kuat tekan yang dihasilkan dengan menggunakan superplasticizer type naphthalene dan dibandingkan dengan beton normal tanpa menggunakan additive. Target mutu rencana adalah fc’ 35 MPa dengan pemakaian dosis additive 1,7% dari berat semen. Hasil penelitian ini menunjukan kenaikan nilai kuat tekan beton speedcrete dengan bahan tambah aadditive naphthalene semakin meningkat seiring bertambah umur beton. Hasil penelitian didapatkan bahwa kuat tekan beton speedcrete dengan bahan additive naphthalene umur 12 jam, 18 jam, 28 jam, dan 48jam adalah berturut-turut sebesar 0,5 MPa, 17,81 MPa, 31,14 MPa, dan 45,77 MPa. Kuat tekan beton normal dengan adanya penambahan 20% air umur 28 hari yaitu sebesar 54,76 MPa. This research aims to determine the maximum compressive strength value of concrete speedcrete using naphthalene additive additive at each test age and compare with normal concrete 28 days. This research was conducted at concrete Lab of PT. Torsina Redikon Pulogadung with eskperimen method. This research used cylindrical test object with diameter 15 cm and height 30 cm. Speedcrete concrete does not undergo the treatment process while the normal concrete test object through the treatment process. Testing compressive strength of concrete speedcrete using Crushing Test Machine tool. In this research the compressive strength was produced by using superplasticizer type naphthalene and compared with normal concrete without using additive. The target quality plan is fc '35 MPa with the use of additive dose of 1.7% of the weight of cement. The results of this research showed an increase in the value of compressive strength of concrete speedcrete with aadditive materials added naphthalene increased with increasing age of concrete. The results showed that the compressive strength of concrete speedcrete with naphthalene additive materials of 12 hours, 18 hours, 28 hours and 48 hours was 0.5 MPa, 17,81 MPa, 31,14 MPa and 45,77 MPa. Normal strength concrete strength with the addition of 20% water age 28 days that is equal to 54.76 MPa.
