Effect of firing temperature on some physico-mechanical properties of ten brick samples, those were composed by feldspars, quartz, alumina-rich spinel, primary mullite and hematite phases, was investigated in accordance with ASTM standards. The brick samples fired between 700° to 1100° C showed 11-23 % water adsorptivity (WA), 19-37 % apparent porosity (AP) and 1.50-1.65 g/cm3 bulk density (BD) indicate good physical properties. The maximum compressive strength (CS) of the fired-bricks at 950° to 1000° C was found to be between 15.6 and 17.1 MPa. At 700°-1000° C firing temperatures, the CS of these bricks is found to be increased exponentially with decreasing of both WA and AP, however it is found to be increased with increasing the BD. Consequently, it can be said that there is good correlation between mechanical and physical properties of the fired-brick samples up to the firing temperature of 1000° C. Bangladesh J. Sci. Ind.

Peat soils naturally have hydrophilic or waterloving character with highly capable of exchanging the cations and cycling the nutrients from the vegetations. This water-loving character is altered to water-repellent character in hydrophobic peat soils. This research was aimed toobserve deeply the functional bunch carrier of hydrophobic and hydrophilic peat soils as shown by FTIR spectra in relation with inherent chemical and physical properties of the soils. Five peat soils consisted of two native andartificial hydrophobic peat soils and one sample of hydrophilic peat soils were studied. Artificial hydrophobic peat soils were yielded by oven-drying the native hydrophobic peat soils at 50 oC for 10 hours. FTIR spectra can distinguish the functional bunch carrier of hydrophobic and hydrophilic peat soils. FTIR spectra of hydrophobic peat soils showed degradation of hydrophilic bunch carrier (OH and COOH) and increase of the hydrophobic bunch carrier (tying aromatic from esther and ether). Chemical analysis of the hydrophobic peat soils also indicated the decrease of OH and COOH content, decrease of CEC , soil total acidity and soil moisture content.

Clay Brick

Physical and mechanical properties of seven ancient clay brick samples of Kathmandu valley consisting of quartz, feldspars, spinel, margarite, muscovite type of mica mineral and hematite were studied using ASTM standards. All the brick samples used in this study have the water absorption, apparent porosity and bulk density in the range of 10-28 percent, 17-33 percent and 1.2-1.8 g/cm3, respectively, while the compressive strength of all the brick samples is found to be in the range of 5-23 MPa. The bulk density of the tile samples is found to be increased with decreasing the water absorption and apparent porosity. The compressive strength of all the clay brick samples can be correlated with their physical properties. Consequently, durability of the ancient bricks is directly influenced by their physical properties of water absorption, apparent porosity and bulk density.

The lightweight aggregate geopolymer concrete (LWAGC) systems were prepared using a lightweight aggregate (LWA) of different size and grading. The diversity in the LWA size and grading led to various physical properties like oven-dry (OD) density, water absorption and total porosity characteristics for the resultant LWAGCs. These physical properties were significantly affected and controlled thermal behavior of the concretes after exposure to elevated temperature of 800 °C. The results of the mechanical and physical test conducted to the unexposed LWAGCs showed that the OD-density and compressive strength increased as the LWA maximum and minimum size decreased. In contrast, the water absorption and total porosity of the unexposed LWAGC were increased with increasing of the LWA maximum and minimum size. Thus, the lowest OD-density LWAGC possessed the highest water absorption and total porosity which resulted in lowest compressive strength, whereas, it has the minimal strength loss after exposure to the elevated temperature. The water absorption and total porosity of the unexposed LWAGCs were indirectly implies the permeability characteristics of the concretes which is controllers the thermal behavior of the LWAGC at elevated temperatures.

Abstract Soil stabilization is the method of improving the physical properties of soil, such as shear strength and bearing capacity of the soil, by using controlled compaction or the addition of admixtures to produce an improved soil material that has all the desired engineering properties. The new technique of soil stabilization uses plastic waste as an alternative material is of outmost crucial since plastic wastes are non-biodegradable and remain intact after being buried in soil for many years. The present study is focused on investigating the effectiveness of utilizing polypropylene clamshell food containers as soil stabilizers. The physical properties of the untreated clayey soil are determined by conducting moisture content, specific gravity, particle size distribution, and the Atterberg limit test. Also, the Standard Proctor compaction test, as well as the unconfined compressive strength test, are carried out to determine the compaction and strength parameters of the soil sample before and after reinforcing with different percentages of polypropylene clamshell food container strips such as 0.4%, 0.8%, and 1.2%. Findings from this study indicate that the addition of polypropylene clamshell food container strips in the clayey soil is capable of becoming a soil stabilizer agent as the optimum compressive strength of the soil was achieved with replacement of 0.8% of plastic strips, along with increasing the Optimum Moisture Content (OMC) while decreasing the Maximum Dry Density (MDD). Successful implementation of polypropylene plastic in soil stabilization can help minimize the volume of plastic waste in the environment, which then leads to developing a sustainable future by utilizing recyclable material as alternative sources in the geotechnical field.

Abstract This study aimed to determine the mechanical and physical properties of the Cross-Laminated Timber (CLT) glued with different amounts of glue. Cost of glue is the outmost importance where it will help in reducing the CLT manufacturing cost. Four different amounts of glue spread were used where the glue that used was phenol-resorcinol formaldehyde (PRF);150, 200, 250 and 300g/m2. The testing of the CLT was conducted by following BS EN 408:2010, BS EN 16351:2015, ASTM D 2718 method B, ASTM D 143-94 and Japanese Agricultural Standard (JAS) 1152:2007. The analysis of physical tests that have been carried out are density, moisture content, shrinkage and swelling of the CLT’s thickness. Meanwhile, the mechanical tests were compression parallel and perpendicular to the grain, three-point bending test (flatwise and edgewise of CLT) and shear test. The highest density was shown by the CLT that using 300 g/m2 which the value was 316.41 kg/m3. Whereas the highest moisture content was shown by CLT that used 250 g/m2 with 15.49% in value. The highest thickness shrinkage percentage was 2.50%, CLT with 200g/m2 while the highest thickness swelling percentage was 5.60% which the CLT used 150 g/m2. For the flatwise bending test, it shows that the CLT that used 300 g/m2 has the highest MOE and MOR value which were 510.63N/mm2 and 8.39 N/mm2. The MOE and MOR value for edgewise bending also shows that CLT that used 300 g/m2 was the best with 1528.70 N/mm2and 13.48 N/mm2. In compression perpendicular to grain test, the CLT with 150 g/m2 shows the highest value of MOE which was 5.89 N/mm2 while CLT that used 200 g/m2 has the highest value of compressive strength with 9.10N/mm2. However, for compression parallel to grain test, the CLT that used 300 g/m2 shows the best performance with 1002.78 N/mm2 and 13.75 N/mm2 of MOE and compressive strength value. Lastly, for the shear test, the highest shear strength value was 0.39 N/mm2 which belongs to CLT that used 150 g/m2. Thus, CLT that used 300 g/m2 of glue spread amount is the best CLT which, the more the amount of glue, the better the performance of the CLT.

Red brick is a building element used in the construction of buildings and made of clay plus water with or without material mixture of other materials. Fly ash and rice husk ash contain silica. Silica is a material that has the nature of pozzolan which can increase the compressive strength of the brick when mixed with the soil. This study aims to determine the effect of the addition of fly ash and rice husk ash (ASP) to the value of compressive strength of clay brick. The process of making the test specimen follows the procedure in the brick factory.Variations of specimens made were normal bricks and bricks with the addition of fly ashand rice husk ash (ASP) used were 5%, 10%, 15%, 20%, 25% and 30% to the weight of clay.The number of test specimens of each percentage of fly ash and rice husk ash (ASP) as much as 12 specimens. The method of testing of red brick strength is referred to SNI 15-20942000. The result of the research shows that the compressive strength of the clay brick has decreased from normal clay brick by 38,97 kg/cm². The biggest decrease in compressive strength value obtaines at clay brick with 30% ashes (48,04%) and the smallest decreased obtaines at clay brick compressive strength in clay brick with 5% ash (5,98%). The decrease of the compressive strength is influenced by the amount of ash addition, water quantity and moisture content.

The awareness to produce biodegradable composite has increased rapidly because of non-toxic and reachable. However, fully biodegradable composite production still low due to the matrix used in the composite is not biodegradable. Thus, this paper presents the study on mechanical and physical properties for the mixtures of corn starch (CS) with different weight percentages of glycerol as thermoplastics corn starch (TPCS) matrix. The selected glycerol contents were at 30, 35 and 40 wt%. The mixtures of CS and different weight percentages of glycerol were made using hot compression moulding at 165°C for 15 minutes to produce the TPCS samples. The mechanical and physical properties were done: the tensile test, hardness test, water absorption test, moisture content test and microstructure analysis under the Scanning Electron Microscopes (SEM). Incorporating 30 wt% loadings of glycerol has increased the tensile strength and hardness. The results show that the addition of higher than 30 wt% loadings of glycerol has decreased the tensile strength and hardness of the TPCS. The physical test results for 30 wt% loadings of glycerol for water absorption test and moisture content show the lowest value than other TPCS samples. However, the density value for all wt% loadings of glycerol does not offer much difference. It reveals that 30 wt% loadings of glycerol in the mixture of CS have shown a good interaction in the TPCS mechanical properties. Based on this finding, the TPCS has huge potential to be used as a matrix to develop a fully biodegradable composite.
