Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself.

Limestone quarrying process is recognized as an initial step in cement production, which produces high content of dust and creates detrimental effects on both the environment and human health. Utilization of agricultural wastes as alternative raw materials is one of the routes to solve such problem. This research is intended to produce eco-friendly light-weight cement blocks from a cement-like material. The cement-like material was synthesized by the low-energy consumption solution combustion technique, using cockleshell and rice husk ash as raw materials. Phase identification analysis of the synthesized cement-like powder indicated the expected phases of tri-calcium silicate (C3S), di-calcium silicate (C2S), tri-calcium aluminate (C3A), and tetra-calcium alumino ferrite (C4AF). To fabricate eco-friendly light-weight cement blocks, the synthesized powder was mixed with Ordinary Portland Cement (OPC), rice husk ash (RHA) and water, with the weight ratio of the synthesized powder:OPC:RHA equal to 25:25:50. The mixture was subsequently cast into light-weight cement blocks. Effects of water contents on compressive strength and bulk density of the light-weight cement blocks were examined. Experimental results revealed that compressive strength of the samples ranged between 1.1 MPa and 2.1 MPa, whereas density ranged from 1.01 g/cm3 to 1.14 g/cm3. The compressive strength of the samples in this study were in a comparable range with that of light-weight concrete defined by Thai Industrial Standards Institute (TISI) and American Concrete Institute (ACI 213,2001). The optimal condition to achieve the standard properties of light weight cement blocks is water-to-binder ratio of 1.3:1 by weight. Results from the current study, therefore, suggested that the eco-friendly light-weight cement blocks obtained from this study exhibited potential practical usage. 2020-10-08T08:36:16Z 2020-10-08T08:36:16Z 2020 Chiang Mai Journal of Science 47,4 (Special Issue II : July 2020), p.700-701 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=11099 http://cmuir.cmu.ac.th/jspui/handle/6653943832/69883 Eng Faculty of Science, Chiang Mai University
