PENGARUH PENAMBAHAN FLY ASH (ABU TERBANG) PADA CAMPURAN BETON CURING DENGAN SUHU 80°C (SELAMA 12 JAM) DI TINJAU DARI KUAT TEKAN BETON

Abstract

Abstract Curing is a procedure after casting that is carried out to maintain the concrete during the hydration process so that the desired concrete strength can be achieved. There are several methods for treating curing based on the temperature used, among others, normal maintenance and maintenance at 80 ° C.This research was conducted to see the effect of fly ash mixture variations on the compressive strength of concrete with normal maintenance methods and curing temperature treatments and also to see the behavior of concrete compressive strength according to the age of the concrete.From the results of the study, the value of concrete compressive strength on cylindrical test specimens of 10/20 cm was treated with 80 ° C curing treatment with a mixture of 0%, 5%, 10%, 15%, 20%, 25%, 30% in obtaining strong results. the highest press occurs at 28 days. then it is known that while the life span of the concrete is higher, the compressive strength is generated Abstrak Perawatan beton (curing) adalah prosedur setelah pengecoran yang dilakukan untuk menjaga beton selama proses hidrasi berlangsung agar kekuatan beton yang diinginkan dapat tercapai. Ada beberapa metode dalam perawatan beton (curing) berdasarkan suhu yang digunakan antara lain, perawatan normal dan perawatan pada suhu 80°C.Penelitian ini dilakukan untuk melihat pengaruh variasi campuran fly ash terhadap kuat tekan beton dengan metode perawatan normal dan perawatan suhu curing dan juga untuk melihat prilaku kuat tekan beton menurut umur beton. Dari hasil penelitian nilai kuat tekan beton terhadap benda uji silinder 10/20 cm yang dirawat dengan perawatan curing 80°C dengan variasi campuran 0%, 5%, 10%, 15%, 20%, 25%, 30% di dapatkan hasil kuat tekan tertinggi terjadi pada umur 28 hari. maka diketahui bahwa semkain lama umur beton maka semakin tinggi kuat tekan yang di hasilkan.
