In this research work, thermal foaming of bottom ash and sodium silicate geopolymer is proposed as a production process for light weight bricks. The composition and temperatures were studied and optimized to get the most suitable intumescence properties for the lightweight construction applications. For this purpose, four different compositions (i.e., 10%, 20%, 30%, and 40% bottom ash (BA)) were cured at four different curing temperatures (CT) (i.e., 200, 400, 500, and 600 °C). Sodium silicate (SS) to sodium hydroxide (SH) ratio was kept constant in order to keep the activation capacity of the solution constant in all the samples so that the effect of composition and CT could be studied effectively. All samples were characterized by bulk density, foamability, compression test, XRD, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), water absorption index (WAI), and weight loss index (WLI). These characterizations finally led to the optimized parameters to get the most appropriate intumescence properties. It was found that bottom ash and sodium silicate geopolymer foams have good potential to produce lightweight aerated blocks.

K. Schum from Sukabumi and Its Potential UsesAbsractGanitri (Elaeocarpus sphaericus (Gaertn.) K. Schum.) is a fastgrowing tree that is widely found in Sukabumi, West Java. It grows in all part of Indonesia. A research was carried out to investigate basic properties (anatomical, physical, mechanical, and chemical) of ganitri wood from the community forest of Sukabumi. The purpose of this study was to determine the potential use of ganitri wood based on its basic properties and local utilization. The results showed that the color of ganitri sapwood was white , and it was not clearly demarcated from the yellow, with fewer figure patterns. The texture was fine with straight to interlocked grain. The wood was soft, not lustrous, and no special odor. Based on the fibre dimensions and derivative values, the quality of ganitri wood fell in Class II as a raw material for pulp and paper. Ganitri had high holocellulose and cellulose levels (70.70% and 54.58%), moderate level in lignin (21.60%), and it contained 3.47% extractive soluble in alcohol-benzene, and 0.81% ash. Based on its air dry specific gravity (0,35), ganitri wood could be classified into wood Strength Class IV. The potential uses of ganitri are for lightweight construction material, tools, furniture, plywood, connecting boards, and other panel products.

Introduction:This study aims to highlight the physicomechanical properties of a new lightweight construction material which is composed of plaster as a binder and dune sand and Expanded Polystyrene Beads (EPS) as aggregates.Methods:For this purpose, different mixtures were designed with different percentages and particle sizes of EPS aggregates in order to test the porosity, the density and the thermo-mechanical properties of the studied composite. Furthermore, Electron Microscopy (EM) visualisation and SEM analysis were used for the study of the structure and the interface “paste-aggregates”.Results and Conclusion:The obtained results showed that the progressive incorporation of an increasing percentage of PSE decreases the density of the plaster composite and consequently improves its thermal properties. As expected, the mechanical strength decreases with the increase of the EPS content, but relatively good mechanical strength can be obtained with low quantities of EPS. Concerning the material structure, it should be noted that the composite appears more or less homogeneous and the EPS beads adhere well to the plaster matrix.

This paper presents the research into the incorporation of coir fiber in concrete blocks for construction purposes. Mechanical tests were performed on concrete samples containing different percentages of chopped coir fibers (0.25, 0.50, 0.75 and 1 by weight of aggregates). Density and water absorption characteristic of the samples were also measured and evaluated in relation to the mechanical properties. It was found that the average compressive strength of the blocks is in the range of 5–6 MPa and the average flexural strength is in the range of 1.04–1.47 MPa, which are lower compared to the results of samples without coir. Nevertheless, the compressive strength range of coir- concrete blocks in this study satisfies the requirements of relevant standards (SNI, AS and ASTM), specifically for non-structural or non-load-bearing concrete blocks. Furthermore, the density of the coir-concrete blocks is between 1230–1536 kg/m3 which fit into the category of lightweight blocks. Based on the results, it can therefore be suggested that the development of coir-concrete blocks is feasible for non-structural, non-loadbearing, lightweight construction material.

Abstract: In recent decades, the use of light-weight materials over heavy-weight materials has increased at a faster rate. When it comes to cost and resource savings, lightweight construction is considered to be more essential. AAC block is a lightweight construction material that provides good acoustic and thermal insulation. In seismic zones, the use of lightweight materials in building reduces the percentage of damages. The goal of this research is to conduct a project comparison study of seismic analysis of buildings composed of lightweight and conventional materials. RSM creates a structural model of a multi-story structure (G+3) and analyses it in Etabs (Response Spectrum Method). Buildings constructed using infill AAC (Autoclaved aerated concrete) blocks and traditional clay brick masonry are designed for the same seismic hazard in conformity with Indian norms. The buildings' analytical results will be compared. The project also aims to familiarise students with Etabs2016. Keywords: Autoclaved Aerated Concrete, Conventional Brick Replacement, Lightweight Construction, Lightweight Material.
