The utilization of the grind lime stone as the mixed material for plaster and fixing of building is rarely used. Limestone has CaO which is 60% untill 80%, it can be decreased the use of cement.
This reaserch has function for knowing how strenght-pressure of mortar and cement mixed by one grind limestone and percentage of grind chalk- stone which has the strenght-pressure of mortar standard. Testing instrument of strength-pressure has cube shaped which has 60 mm x 60 mm x 60 mm. The testing strength pressure of material was tested in Material and Construction laboratory, civil engineering of Diponegoro University Semarang. It was tasted when the mortal was 8 days made. Mortar has been given the grind limestone based on different content.
It contents cement : sand :grind chalk-stone 1: 6:2 and 1:7:3. Mortar produced the highest standard of strenght-pressure than type of N Mortal. In this composition has 1:7:3, mortar can be holded more than 10,56 kg/cm2 and it can decrease using of cement more than 25% without losing the strenght-pressure of mortar based on Indonesia Standard 15-3758-2504
