Abstract

Development in the field of construction in the modern era shows a very rapid development, including in the construction of housing, offices, hospitals and so on. Concrete as a construction material has long been used and widely applied by the community because it has advantages easily formed according to construction needs. The development of concrete technology has also continued to develop with the presence of high-strength concrete. The process of making lightweight concrete certainly requires mixed materials that have low specific gravity. One alternative material that can be used is newsprint and fly ash, both materials are materials that have a low specific gravity and are easy to work on, the addition of fly ash and newsprint so that the relationship of compressive strength and weight of concrete influence each other, the more addition of fly ash and newsprint, the compressive strength increases and the weight of the concrete increases.

Abstract

Geopolymer mortar is a mortar based mixture without using porland cement as a binding material replanced with rice husk ash and marl, using a mixture of sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) to determine the effect of using huskk ash rice and stone mortar napal geopolymer conducted research using experiment in the laboratory using 5x5x5cm3 specimens the ratio of rine husk ask and stoone marl 75%:25%,50%:50%,25%:75% as much as 45 test specimens, compressive strength testing aged 3, 7, 14, 21, and 28 days. From testing the maximum strength is 17,73 Mpa obtained at the age og 28 days for rice ash and stone marl 25% : 75% from the results of the compressive strength shows that the addition of stone and the reduction of ash made of rice husk compressive strength increases.
