Abstract


In this paper, refractory bricks were developed by using locally obtainable materials like red
clay and glass sand in Bangladesh. The Preliminary investigation was conducted by measuring the
compressive strength of bricks produced by adding a range of materials with red clay in different proportions.
It was found that the brick containing 30% white Portland cement and 10% glass sand with red clay (60%)
demonstrated the highest compressive strength (36.20 mpa). The suitability of refractory bricks was
evaluated by examining their physical and thermal properties. The evaluation of these parameters revealed
that the properties are suited with refractory requirements such as low water absorption (4.58%), moderate
apparent porosity (13.32%), preferable bulk density (2.64 gm/cm3
), less linear shrinkage (3.10%), better
refractoriness (1408 ºC), thermal conductivity (1.3 W/m.K) and thermal shock resistance (15 cycles). The
mineralogical analysis carried out by XRD exhibits the presence of Quartz and Bavenite phase. The
performance evaluation shows that this brick is able to fit most of the criteria of refractory brick needed for
practical purposes. Since local materials were utilized, the proposed method can be used for the manufacture
of low-cost refractory brick in Bangladesh.
