【 摘 要 】

This concrete aims to know the effect of SikaBond additive material on concrete connection. Made three types of testing of the shear strength, tensile strength and flexural strength of the connection. For flexural tests measuring 15 x 15 x 75 cm with 45° grafting angle, shear strength and tensile strength with size of 5 x 10 x 20 cm which are both bonded. The planned concrete quality of F'c 22.5 Mpa, ACI method of modifying Fas value 0.5, Slump value 93.33 mm. Strong flexure without voltage connection 34.69 Kg / cm2, beam grafting with the addition of a voltage cycles of 32.92 Kg / cm2. Voltage beam with the addition of cement water 38,41 Kg / cm2. The comparison of the shear stress test voltage of the cementless joint of the cement is 15.57 Kg / cm2, the beam which is grafted with the addition of a 12.48 Kg / cm2 voltage cyclone, decreased by 19.81% from without cement. The beam stress with the addition of cement water of 9.60 Kg / cm2 decreased by 38.34%, the cementless block. The connection with the addition of a stronger cyclone retains a shear force than the junction of water. Comparison of tensile strength test of cement tensile strength without cement connection 3.67 Kg / cm2, beam grafting with addition of 3.15 Kg / cm2 voltage SikaBond decreased 14.18% from without cement. The beam stress with the addition of 2.88 Kg / cm2 of cement water has decreased by 21.46% of the beam without cement connection. The connection with the addition of a stronger cyclone retains tensile strength than the connection with cement water at 28 days.
