Study of the Mix Cement Properties of Mortar Cement Used in Masonry and Plaster from the Waste Biscuit Firing of Ceramic

Abstract

The purpose of this study is to study the characteristics of cement mixes and to find out the right qualities according to Mortar Cement in terms of flow formation period and compressive strength. This work was tested for the properties of cement Mortar at Research and Development Department, Department of Concrete Testing, Royal Irrigation Thailand in ASATM C 91-97C, and ASTM C 807-89 standard. The results of the study indicated that the formula of Mortar Cement A1 flow characteristics 112, the formation time was 45 minutes and the compression strength was on the average of 39.35 MPa. Mortar Cement A2 flow characteristics 112 formation time was 45 minutes, compression strength was on the average of 25.35 MPa. Mortar Cement A3 properties of flow 118, formation time was 60 minutes, Compression strength was on the average of 17.73 MPa. Mortar Cement A4 features of flow 113, formation time was 55 minutes, compression strength was on the average of 15.33 MPa. Mortar cement A5 features of the flow 114, formation time was 55 minutes compression strength was on the average of 15.30 MPa. From the experimental result, we found that the best formulation is Mortar Cement A1, which has the highest characteristics in every property. From this study Molar cement, a material in the pozzolanic group, it is suitable for production and development in repairing old buildings or historic site. Mortar Concrete has less expansion, but high density of water slow rate ofdevelopment due to slow reaction with water. However, the compressive strength in the back is the same, the old work with the repair parts do not crack because of the surface tension, the material affected by rapid dehydration.
