Abstract In recent years, there has been a lot of attention paid to the use of textile sludge waste-based products in the building industry to develop ecologically friendly construction materials. An experimental examination of the characteristics of bricks incorporating textile sludge waste and fly ash is presented in this work. In fly ash bricks, fly ash is used to replace textile sludge waste in the following proportions: For the blend percentage of cement, fly ash, and quarry dust, a 230mm × 100mm × 75mm sample size was used. For varying amounts of the components indicated previously, the findings indicate how compressive strength and water absorption fluctuate with curing age. Then we can cast bricks with various mixed proportions of cement, sludge waste, fly ash, and quarry dust using the 230mm × 100mm × 75mm specimen size. After that, the weight, compressive strength, and water absorption of textile sludge with different concentrations of fly ash bricks were compared. This inquiry is primarily concentrated on maximizing the compressive strength of newly produced bricks while limiting weight density and water absorption through extensive laboratory work. The recognition of elements influencing the diverse qualities of bricks is a clear purpose of pursuing this issue as project work.

Abstract. Our project was built with cenosphere material and low-density brick. The cenosphere bricks may be lighter and stronger than traditional fly ash bricks. Cement is used to replace the cenosphere in fly ash bricks in the following proportions: 230mm x 100mm x 75mm sample size for blend percentage of cenosphere, fly ash, and quarry dust. The results show how compressive strength and water absorption vary with curing age for mixed proportions of the materials mentioned previously. Then we can use the 230mm x 100mm x 75mm specimen size to cast bricks with various mix proportions of cenosphere, fly ash, and quarry dust. The weight, compressive strength, and water absorption of the cenosphere with various proportions of fly ash bricks were then compared. Via comprehensive laboratory work, this investigation is primarily based on optimizing the compressive strength of newly formed bricks thus minimizing weight density and water absorption. A definitive goal of undertaking this point as project work is to recognize factors influencing the different properties of bricks.

Brick is one of the foremost extensively used construction materials for masonry purpose. Emphasizing the possibility to convey imperative effect against India's present-day lodging and industrial waste concerns are of paramount importance. This could be achieved by fabricating sustainable products using industrial wastes. Alkali-activated products are assumed to be eco-friendly and economical, leading to Portland cement-free products. This project work is an attempt to discover an eco-friendly brick for construction purposes by totally replacing the normal brick components by wastes from many industries. For the investigation purpose, we developed geopolymer bricks by utilizing fly ash as the binder, foundry sand as the fine aggregate, bentonite as an additive for improving its properties and finally the alkaline arrangement (a blend of NaOH and Na2SiO3 ). Fly ash combines with alkalis such as Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3 ) creating an alumino-silicate gel, that shows properties similar to that of cement and it can be used as the environment-friendly binding material. The design mix proportions of the current work are 0.54:0.44:0.04 (fly ash: foundry sand: bentonite), solutions to fly ash ratio is 0.5 and the ratio of Na2SiO3 to NaOH is 1.5. The basic characteristics of bricks such as compressive strength, water absorption capacity, density, soundness, efflorescence, and hardness were tested. It attains a compressive strength value ranging between 6-25Mpa, water absorption value in between 5-12% and also the developed bricks were light in weight. Also, the final conclusions were drawn after comparing the test results with other geopolymer bricks and clay burnt bricks. Geopolymer bricks seem to be incredibly beneficial as they will amalgamate a large quantity of industrial wastes. The utilization of waste raw materials (except for alkaline activator solution) resulted in a substantial reduction in the estimated production cost of the bricks.

Concretes based on alkaliactivated binders have attracted considerable attention as new alternative construction materials, which can substitute Portland Cement (OPC) in several applications. These binders are obtained through the chemical reaction between an alkaline activator and reactive aluminosilicate materials, also named precursors. Commonly used precursors are fly ash (FA), blast furnace slag (GBFS), and metakaolin. The present study evaluated properties such as compressive strength, rate of water absorption (sorptivity), and chloride permeability in two types of alkaliactivated concretes (AAC): FA/GBFS 80/20 and GBFS/OPC 80/20. OPC and GBFS/OPC* concretes without alkaliactivation were used as reference materials. The highest compressive strength was observed in the FA/GBFS concrete, which reported 26,1% greater strength compared to OPC concrete after 28 days of curing. The compressive strength of alkaliactivated FA/GBFS 80/20 and GBFS/OPC 80/20 was 61 MPa and 42 MPa at 360 days of curing, respectively. These AAC showed low permeability to the chloride ion and a reduced water absorption. It is concluded that these materials have suitable properties for various applications in the construction sector.

Abstract Sewage waste is a crucial factor in the disposal and also harmful to the environment. The growing demand for waste utilization is construction and demolition waste. This study aims in preparing a brick using construction and demolition waste and sludge waste. The materials such as fly-ash, cement, construction, and demolition waste, and sludge waste are used. The sludge content was added at constant percentage of 30%, 40% and 50% with different proportions such of fly-ash, cement and demolition waste of 3:2:2, 1:3:2, 2:1:2, 2:3:2, 2:3:1, 2:2:1, 2:2:3, 3:2:1, and 1.5:1.5:2 respectively. The physical characteristics such as compressive strength, bulk density, and chemical characterization such as water absorption, pH, and detection of heavy metals were carried out. The test results infer that increase in the content of sludge, the strength decreased. Maximum compressive strength of 14.5 Mpa was achieved for the ratio of 2:3:2 at 30% of sludge. The maximum bulk density was achieved at 30% of sludge. This was attributed due to the presence of organic properties in the brick. Moreover, the water absorption increases with an increase in the percentage of sludge.

In this study, the properties of foamed sandcrete solid block (FSSB) with varying percentage of sand replacement with fly-ash were investigated. These properties include workability, wet and dry density, stability, water absorption capacity and compressive strength. 150mm cube specimens were used for the determination of both the compressive strength and the dry density of the FSSB. The plastic density was investigated using a container of known volume, and its workability determined using the slump test. The fly-ash content was varied from 0 to 50% at interval of 10%. The specimens without the fly-ash served as the control. At the designed density of 1500kg/m3, the results for the control specimens at 28 day curing age was 3.74N/mm2. As for 50% sand replacement with fly-ash, the compressive strength were 2.37 N/mm, and 3.31 N/mm2 at 7-days 28-days curing age respectively, both satisfied the minimum compressive strength of 1.8N/mm2 and 2.5N/mm2 at the curing age of 7-days and 28-days respectively for conventional sandcrete block for building wall unit as allowed by Nigerian Industrial Standard (N.I.S). The result also shows an appreciable decrease in density of FSSB with 1411.8kg/m3, as compared to dense sandcrete solid block with average of 1950kg/m3, which will significantly reduce the overall dead load of the building structure. FSSB with 50% sand replacement with fly-ash also showed a much improved water absorption capacity of 9.81% as control specimen of 11.73%. Fly-ash can be used to reduce the quantity of sand used in FSSB production; thus ridding our environment of potentially harmful wastes, as well as reduce the consumption of non-renewable resources. Keywords— Foamed Sandcrete, Compressive Strength, fly-ash, dry density, stability, cement

Lightweight construction is aimed to achieve a sustainable feature by reducing transportation frequency and construction materials usage during construction phase. Lightweight precast concrete may serve an alternative for the lightweight construction. There are rarely application can be found for structural members as lightweight panels always to be used for secondary or non-load bearing members. This paper presents an experimental study on properties (compressive strength, splitting tensile strength, water absorption) of lightweight foamed concrete (LFC) at two different curing methods. LFC with densities of 1500, 1700, and 1800 kg/m3, cement-sand ratio of 2:1 and water-cement ratio of 0.5 were investigated. The results showed LFC can be produced with the properties ofdensity range of 1500 to 1800 kg/m3 and corresponding compressive strength of 10 to 39 MPa. The higher the density of LFC, the less the water absorption for all the curing method considered, the highest and the lowest water absorption was 11.3% and 2.0% for 1500 kg/m3 cured in water and 1800 kg/m3 cured in air respectively. Compressive strength of LFC increases with age and density while water cured LFC has high compressive strength. Splitting tensile strength increases with density of LFC, but air cured LFC has more splitting tensile strength than water cured of the same density. The highest splitting tensile strength recorded was 3.92 MPa for 1800 kg/m3 cured in air, which was about 16% of its compressive strength at 28 days of curing age. These properties are important and can be applied to LFC precast structural members with air or water curing method which have less references for LFC in structural usage.
