Thermo-physical and Mechanical Properties of Clay Bricks Produced for Energy Saving

Fired clay bricks are widely developed by focusing on the use of several wastes with the aim of obtaining lightweight materials. Despite research having provided positives experiences, most of these showed an important reduction of compression strength. This issue must be highlighted in particular, when seismic areas are considered. However, despite compression strength decreases in some cases the energy that can be absorbed by the brick might be increased. Hence, this paper tests and shows physical and mechanical properties of newly fired clays made by adding different percentages of sawdust. Results are used for calculating the response of an individual one-story house to medium intensity earthquakes. It is concluded that the use of bricks, with up to 5% sawdust added, is an ecological way for recycling these agro-wastes, while its behaviour against earthquakes performs better than other solutions, such as common perforated bricks.

Cooking Temperature

Current research in the field of building materials is oriented towards the recovery of waste to ensure the lightening of certain building elements and energy saving. The objective of this study is to produce a new bricks by adding sawdust to clay mixtures. The first part of this experimental work consists on detremining the proper manufacturing process and cooking diagram for these new bricks. In the second part, the effect of the maximum cooking temperature, the firing phase time's of the bricks and the sawdust prportion on the physical and mechanical properties of the new bricks have been studied. The studied properties are the absorption ratio, the unit weight and the compressive strength. The results showed that the addition of an increasing amount of sawdust tends to modify the physical and mechanical properties of the cooked samples. The presence of sawdust reduces the number of connections between the clay grains and produces a lighter, more absorbent and less resistant material. Finally, the results showed that the manufacture of bricks based on sawdust is possible.

Coconut Fibre

Over the year, agricultural establishment produced many types of waste in its daily operation. Coconut fibre for example is one of the most abundant agricultural wastes produced in Malaysia. Despite the massive amount of the waste produced, the standards of waste management in Malaysia are still poor. The main purpose of this study is to focus on the potential of coconut fibre utilization into fired clay bricks. The objectives of this study are to determine the characteristics of coconut fibre, to identify the gas emissions during firing process from coconut fibre brick and to investigate the physical and mechanical properties of from coconut fibre (1%, 3% and 5%) incorporation into fired clay brick. All the bricks were fired in a furnace up to 1050°C at 1°C/min. The gas emissions that were measured are carbon monoxide (CO), carbon dioxide (CO2) and sulphur dioxide (SO2). Based on the three gases, the results showed that CO2 is the highest gas emission produced during the firing process. Physical and mechanical properties tested are total shrinkage, dry density and compressive strength. Results found that by adding different percentages of coconut fibre, most of the properties were complied with the standards except for the compressive strength of 5% of coconut fibre in clay brick. Therefore, the utilization of coconut fibre could be one of the alternative disposal methods for agriculture waste and it will also provide low-cost material for brick that produce adequate physical and mechanical properties.

Black Alder

Alder gains increasing popularity just like alternative to expensive raw materials. Detai-led technique of the studies is proposed. The basic physical and mechanical properties of black alder wood are given, its properties as a material for furniture and interior decoration are examined. Beforehand dehydrating pro-cess of alder was mathematically modeled, values of transient humidity and other key operating parameters were obtained, and then practical industrial drying on parabolic modes was implemented. These modes include four stages with the initial warming and final WTP.

Clay Bricks

The objective of this study is to investigate the effect of red clay, grog and cement content (5,10,15,20%) on unfired clay brick’s properties. The comparative properties of construction bricks produced by the community fulfilled the requirements of Thai industrial standard (TIS 77-2545) for brick processing in Small and Micro Community Enterprise of Clay Brick Making Group in Son Bun Reung village. The physical and mechanical properties were tested consisting of the volume shrinkage, bulk density, appearance porosity, moisture expansion, slaking, compressive and fractural strength. The result showed that physical-mechanical properties were improved by the addition of cement. The unfired clay brick consisting of 100% grog and 20% cement had 4.5% shrinkage value. The bulk density and appearance porosity were 1.77 g/cm2 and 3.5%, respectively. The fractural strength of unfired clay bricks was 41.2 kg/cm2. The compressive strength of unfired clay bricks was 282.4 kg/cm2. The clay bricks were not slaking.
