Properties Of Mortars Incorporating Brick Dust

Today, pozzolan and cementitious materials plays an important role in concrete. Wastes of industries and constructions which have pozzolanic or cementitious property, not only can reduce environmental pollution and energy consumption of construction industry [1]. Industrial waste management is one of the major environmental problems in Turkey. Therefore, recycling and reuse of industrial wastes play vital role both in solving industrial waste problem and in getting benefit from it The problems could be reduced to a large extent by using these waste materials in cement concrete. Brick dust is waste material that generated from brick klins These wastes are dumped openly, which not only occupy land but also create environmental pollutions. These problems could be reduced by recycling these waste materials in concrete. This paper investigated the usability of brick dust on mechanical properties of cement mortars as experimentally. For the production of mortars were used rilem sand, cement and brick dust. Cement type used in this study was CEM I 42.5. It was tested in accordance with TS EN 197-1 [2]. The sand used in this research was of standard Rilem Cembureau type. The standard sand contained 90% SiO2. Brick Dust Waste (BD) was used in this study. It is a waste from the cutting of fired clay bricks. For this purpose, The brick dust replacements were (0%, 2%, 4%, 6%, %8 and %10) by weight. Prismatic samples (40*40*160 mm) were cast and cured for 28 days. Compressive and tensile strength of mortar was investigated and all experiment result were compared with each other. The compressive and tensile strength were carried out after at least 28 days of curing age in accordance with TS EN 196-1 [3]. All the values are the average of three specimens tested in each case during the testing program of this study. The results are discussed as follows: The average strength of concrete was tested after 28 days of curing. The compressive and tensile strength was found to decrease with increase in percentage of replacement but the workability was found to be good. The mortar containing 2% of brick dust had higher compressive strength than 4%, 6% 8% and 10%. The mortar containing up to 2% and 4% of brick dust in 28 days exhibited comparable results with the TS value. Therefore, brick dust can be used in producing sustainable, economical, and environmentally friendly cement by reducing the amount of portland cement consumed.
