Pengaruh Penambahan Zeolit dan Sikament-LN terhadap Kuat Tekan Beton
Sari
Stength of concrete is fundamentally a function of the volume of voids in it. If the porosity of concrete is getting lower, the strength is increase, but workability more difficult. Concrete has a very high strength, if it has a very low porosity. To make concrete with small or little porosity and workable use pozzoland and superplasticizer.
In this research about concrete which added Zeolit as pozzoland and Sikament-LN as superplasticizer. Percentage of pozzoland are 0%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10% and Sikament-LN 1% with 10% water reducer. The age of speciments test are 28 days.
The result of this research show that the concrete strength increases until additional Zeolit 9% with additional Sikament-LN 1% and 10% water reducer. Concrete Strength decreases at additional Zeolit 10% with additional Sikament-LN 1% and 10% water reducer. The maximum concrete strength is 45.559 MPa or increase 18.015 MPa (65.405%) compared with concrete with additional Sikament-LN 1% and 10% water reducer.Teks Lengkap:
