Abstract

The effect of andesit powder addition variety on the properties of the mortar compressive strength was carried out. This study aims to investigate  the effect of andesit powder addition variety on the properties of mortar compressive strength which is added on mortar blend by comparing mortar without the addition of andesit powder. Mortar with various andesit powder contents (10, 20, 30, 40 and 50 % by weight respectively) as partial replacement of portland cement at the age of 7, 14 and 28 days curing. The results show that the compressive strength of each ages with andesit powder addition is higher than mortar without the addition of andesit powder. The highest compressive strength are 11.8, 14.3 and 17.4 MPawith andesit powder respectively and 5.6, 7.56 and 11.00 MPa regarding to the mortar without andesit powder. Therefore 30% seems to be the optimal as partial replacement cement level. The results show with decreasing porosity on the mortar, the density will be greater and solid, it will decrease the absorption. The results of X-Ray flourescene indicate that the chemical element of Si, Al and Fe increase with increasing the dosage of andesit powder which is added on mortar blend. Consequently the Ca element may decrease by addition of andesitpowder on mortar endlessly. The X-Ray Diffraction shows the coestite and hematite phase after temperature 900 oC calcination.
