PENGARUH PENAMBAHAN SERAT ROVING PADA MORTAR (Tinjauan Terhadap Kelecakan, Kuat Tekan, Kuat Tarik, Dan Kuat Rekat)

Mortar is a building material that made of water, adhesive materials ( mud, lime, portland cement ), fine aggregate ( natural sand, pieces of the wall ). This study was conducted to determine the effect of fiber rovings to compressive strength, tensile strength, and strong “rakat”. Composition without lime mortar mix is 1 cement ( PC ) : 8 Sand ( Ps ) with the addition of fiber rovings ( SR ), respectively : 0SR, 0.1 SR, 0.2 SR, 0.3 SR, 0.4 SR. Composition of the mixture with lime mortar is 0.5 Pc : 0.5 Kp : 8 Ps with additional fiber rovings each 0SR, 0.1 SR, 0.2 SR, 0.3 SR, 0.4 SR. Tests performed is workability, compressive strength, tensile strength, and a strong adhesive mortar. Compressive strength testing using a cube -shaped specimen with a size of 50 x 50 x 50 mm, for tensile strength testing using the test object shaped like a figure eight with a size of 75 x 50 with the middle 25 mm, and strong adhesion to the brick specimens were prepared perpendicular. The results for the mortar without lime scatterplot shows the test by 95 % - 103.5 % with fas value generated between 0.6 to 0.75 the highest compressive strength values at a ratio of 1 Pc : 0SR : 8 Ps is equal to 55.558 kg/cm2 , smallest value of compressive strength occurs at a mixture ratio of 1 Pc : 0.4 SR : 8 Ps is equal to 26.952 kg/cm2, the highest tensile strength values at a ratio of 1 Pc : 0.2 SR : 8 Ps is equal to 13.774 kg/cm2, strong values the smallest drop in mixing ratio 1 Pc : 0.4 SR : 8 Ps is equal to 7.048 kg/cm2, while for lime mortar scatterplot shows the test by 95 % - 103.70 % with fas value generated between 1.1 to 1 , 2 , the highest compressive strength values obtained in 0.5 ratio of Pc : 0.5 Kp : 0SR : 8 Ps is equal to 38.748 kg/cm2 , the smallest value of compressive strength occurs at a mixture ratio of 0.5 Pc : 0.5 Kp : 0, 4 SR : 8 Ps is equal to 17.709 kg/cm2, the highest tensile strength values in comparison Pc 0.5 : 0.5 Kp : 0.2 SR : 8 Ps is equal to 8.019 kg/cm2 , the smallest value of tensile strength occurs at a ...
