Achieving sustainable construction in the developing countries Of Southeast Asia

Sustainable construction is a way for the building industry to move towards achieving sustainable development, taking into account environmental, socioeconomic and cultural issues. Differing approaches and differing economic markets lead to different priorities. This paper presents the construction scenario of Southeast Asia and the developments in sustainable construction taking place in the region. Barriers to the implementation of sustainable construction are discussed. A list of recommendations was proposed to drive sustainable construction in the region. In conclusion, the status of sustainable construction in Southeast Asia is still in its infancy. The lack of awareness, training and education and ineffective procurement systems are among the major barriers for sustainable construction in the region. In some countries public policies and regulatory frameworks do not encourage the development of the construction sector. Besides the needs for capacities, technologies and tools, total and ardent commitment by all players in the construction sectors including the governments and the public at large are required in order to achieve sustainable construction in South-East Asia

The effects of electrolytes on the liquid limit of clay

The liquid limit of clay treated with electrolytes were investigated and examined with respect to electrolyte types and concentration, time-dependent effects, and mineralogy of clay. The findings indicated that the types and concentration of electrolytes in the pore fluid of clay have a marked effect on the liquid limit of clay. Ageing has a pronounced effect on the liquid limit, particularly for clay treated with cementing agent

Temperature behavior visualization on rubber material involving phase change simulation

Material engineers are excited with the design of a new rubber product through the development of a new composite of rubber product. Our research contributes in developing the mathematical simulation based on Gauss-Seidel Red-Black and Gauss-Seidel method to solve the temperature behavior of the rubber elasticity, strength, entropy and classical experiments through reference publications and stimulating rubber physics research elsewhere. The temperature behavior leads to the partial differential equation of heat transfer problem involving phase change simulation. The prototype of the algorithm implement on Linux operating system using C language.Roziha Darwis, Norma Alias, Nazeeruddin Yaacob, Mohamed Othman, Nurashikin Abdullah, Teh Yuan Yin

The effectiveness of electrodes types on electro-osmosis of Malaysian soil

Electro osmosis technique is known as an effective method for stabilizing clay. The process involves passing an electrical current through soil mass by dissolution of electrode material or by introduction of chemical solution at the electrode. The dewatering process induced by the introduction of chemical at the electrode would results in the improvement of shear strength properties. This paper presents the results of a series of laboratory tests on the electro osmosis treatment of Kahang clay by the dissolution of different anode materials i.e. ferum, aluminium, and cuprum. A constant voltage at 30 V was applied for 672 hours to each different electrodes cell. The dewatering process was monitored and the shear strength was measured both before and after treatment. The results revealed that the different types of electrodes resulted in the same cumulative water discharge. However, the improvement in strength is dependent on the type of electrodes
