TY - JOUR ID - TI - Optimum Design of Concrete Mixture Used to Bonda Plastic Pipes with aConcrete Manhole Optimum Design of Concrete Mixture Used to Bonda Plastic Pipes with aConcrete Manhole AU - Mohammed SalihAbd - Ali Mohammed SalihAbd - Ali PY - 2015 VL - 11 IS - 21 SP - 1 EP - 17 JO - Journal of Misan Researches مجلة ابحاث ميسان SN - 18156622 27897354 AB - This paper presents a laboratory trial procedure for optimum design of concrete mixes using locally available ingredients. The optimization procedure is formulated as finding the best bond between the plastic pipes and the manhole by trying different combinations of concrete mixtures with constant water-cement ratio at local ambient temperature. In this research, effect of Styrene-Butadiene Rubber (SBR) latex on compressive strength and bond strength of concrete has been studied. To simulate the conditions that occur in the field, sixty six slab specimens were poured. The average of two slabs represented one case. The specimens were tested to determine the bond strength between plastic pipe and the slab. Results showed that the increase of the ratio of SBR to water led to an increase in the compressive strength and bond strength even if there was an increase in the opening diameter of slab. Therefore the recommendation was using SBR in dosage equal to (25 %) by volume of water with concrete mix (1 : 1 : 2).This paper presents a laboratory trial procedure for optimum design of concrete mixes using locally available ingredients.
