Abstract
This work aimed to study the effect of blend ratio on properties of Agro stone caulking materials. With the experiment, fixed ratio pumice filler and bagasse were used. Magnesia cement was used as binding material. Caulking were produced from different proportion of magnesium oxide and magnesium chloride brine solution (0.9:1, 0.95:1, 1:1, and 1.2:1, 1.32:1 kg per liter) with concentration of 28, 30, 33, 36 and 42 wt/wt % brine solution. The caulking materials were characterized by physical properties, mechanical properties, and free chlorine ions. After curing for 14 days and 28 days, the common mechanical properties tensile, compressive, and flexural bending strength was measured with the assistance of computerized testing machines according to testing procedures. The minimum and maximum water absorption capacities were 14 and 26.4% respectively. The optimum tensile, compressive and flexural bending strength of the experiments were 3.8 MPa, 25.8MPa, and 23.12MPa respectively with the ratio of caulking material 1:1 kg of MgO to a liter of MgCl2. The free chloride ion was reduced to 20% by adding 5%wt zeolite. The optimum mixing ratio was 1:1 with 36% of brine solution. The study shows the potential of high strength, and low corrosion biobased composite ecofriendly materials for the productions of agro stone composite caulking materials.
