This study involves the experimental investigation of effect of fly ash and dry sludge on the properties of fly ash bricks. On seeing the present day demand for bricks, an attempt is made to study the behavior of bricks manufactured using, different waste materials like dry sludge and fly ash. The main aim of this work was to compare the compressive strength of the bricks. The disposal of sludge has always been by dumping in the soil, this has hazardous effect on the air and environment at large. They can be recycled for use in construction industry without producing any harm to human and environment. Research has shown that they can be used in manufacturing of cement. Sludge and fly ash mixed with Quarry dust and cement in various percentage keeping the Quarry dust and cement with constant percentage of 30% and 20% respectively, while fly ash is replaced with sludge from 0% to 100% consequently with 20% replacement. The result shows that fly ash and sludge together can be used in the alternative bricks, the compressive strength and water absorption is good and weight of the brick is reduced up to10% from the nominal bricks.

This research paper aims at investigating the effects of fly ash as cement replacement in green concrete made with partial replacement of conventional coarse aggregates with coarse aggregates from demolishing waste. Green concrete developed with waste materials is an active area of research as it helps in reducing the waste management issues and protecting the environment. Six concrete mixes were prepared using 1:2:4 ratio and demolishing waste was used in equal proportion with conventional aggregates, whereas fly ash was used from 0%-10% with an increment of 2.5%. The water-cement ratio used was equal to 0.5. Out of these mixes, one mix was prepared with all conventional aggregates and was used as the control, and one mix with 0% fly ash had only conventional and recycled aggregates. The slump test of all mixes was determined. A total of 18 cylinders of standard size were prepared and cured for 28 days. After curing the compressive strength of the specimens was evaluated under gradually increasing load until failure. It is observed that 5% replacement of cement with fly ash and 50% recycled aggregates gives better results. With this level of dosage of two waste materials, the reduction in compressive strength is about 11%.

Ion Penetration

Even though the use of fly ash in concrete is nowadays a common practice, its relatively slow pozzolanic reactivity hinders its greater utilization; hence efficient methods of activation are on demand. This study was carried out to evaluate the influence of lime as a chemical activator on the mechanical and durability properties of high strength fly ash concrete. Mixtures were made with 0, 30, 40, and 50% of cement replaced by low calcium fly ash. Corresponding mixtures were also made with the same amount of fly ash and addition of 10% of lime to each mixture. For each concrete mixture, slump, compressive strength, water absorption, sorptivity, apparent volume of permeable voids, and resistance to chloride-ion penetration were measured. The results obtained showed that addition of lime improved the compressive strength significantly at all ages. The strength of all the fly ash mixtures containing lime surpassed that of the corresponding Portland cement mix at 60 days. Addition of lime also improved the sorptivity and resistance to chloride-ion penetration of the fly ash concrete. It however increases the water absorption and the volume of permeable voids of the fly ash concrete.

Buildings made of earth material is an attempt for sustainable development to overcome the threats of rapid pollution rate caused by huge application of cement in construction industry almost in all forms as building blocks, all kinds of structural elements and infrastructure. The main objective of this project is to identify the better stabilization material for stabilized earth blocks for partial replacement of cement in the manufacture of CSEB’s. The scope of work is to achieve a harmonious integrated performance of buildings with physical environment by using natural earth material for preparing building blocks. In this project fly ash and quarry dust has been compared to find out the most suited stabilization material for CSEB’s providing efficiency as well as sustainability as a substitute material for cement. In this project CSEB’s prepared using 70% laterite soil and 30% of cement has been compared with specimens in which cement is replaced with fly ash and quarry dust in ranges of 10% and 20% of its weight. The 28 days compressive strength results shows 12.5% increase in strength for 10% optimum replacement of cement using fly ash and about 7.5% increase in strength for 10% optimum replacement of cement using quarry dust. The reduced water absorption has been notified in CSEB’s using fly ash and quarry dust which will facilitate good bonding with fresh mortar by avoiding high rate of water absorption from fresh mortar by blocks finding its effective application in construction of load bearing walls for general buildings.

The environmental impacts of the construction industry can be minimised through using waste and recycled materials to replace natural resources. Results are presented of an experimental study concerning capillary transport of water in concrete incorporating densified expanded polystyrene (EPS) as a novel aggregate. A new environmentally friendly technique of densifying was used to improve the resistance to segregation of EPS beads in concrete. Twelve concrete mixes with three different water/cement ratios of 0.6, 0.8 and 1.0 with varying novel aggregate content ratios of 0, 30, 60 and 100% as partial replacement for natural aggregate by equivalent volume were prepared and tested. Total absorption, absorption by capillary action, and compressive strength was determined for the various concrete mixes at different curing times. The results indicated that there is an increase in total water absorption (WA) and capillary water absorption (CWA) and a decrease in compressive strength with increasing amounts of the novel aggregate in concrete. However, there is no significant difference between the CWA of control and concretes containing lower replacement level.

Flyash is one of the largest emerging products in the construction industry. The fly ash is the by-product which is widely used in brick manufacturing plant. The flyash reduces the cement content and also overcomes several disadvantages. Simply, it is a step towards eco-friendly environment. Though the flyash brick has many advantages, it has lower strength at initial stages due to low hydration. In this study, the experimental investigation was carried out to find the optimum mix ratio of various compositions of fly ash bricks. The brick specimens were casted on different compositions of cement, flyash, eco-sand and various other admixtures. On addition of these admixtures the early compressive strength was also high and a quick hydration was observed. The tests were conducted on 3rd, 5th, 7th and 28th day. The results suggest that the maximum strength was obtained for the composition of fly ash, ecosand, cement and silica fume.

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.

This research was carried out to investigate the effect of partially replacing cement with quarry dust in cement-sand mortar. Tests including setting times, water absorption, compressive strength and density test were carried out on mortar with cement partially replaced with 0%, 5%, 10%, 15%, 20%, 25% and 30% quarry dust and presented. Experimental results show that replacement of quarry dust as partial replacement of cement in cement-sand mortar decrease the initial and final setting times of cement paste and increase the water absorption of the mortar. The partial replacement shows an improvement of compressive strength at 5% quarry dust content after which there is a decrease with increase in quarry dust content at all the ages. The increase in compressive strength at 5% indicates possible pozzalanic activity at that level. Thus quarry dust can be utilized as cement replacement material at 5% dust content. Above this it can be utilized as fine aggregate replacement for use in low-strength mortar applications

Groundnut Shell Ash

Concrete plays a prominent role in the construction industry. In the present scenario, there is a shortage of this material so there is a need to find alternatives to replace it in the concrete. In order to overcome this situation; many waste products which are available freely like a paper waste, red mud, rice husk and plastic waste can be used.  Among all of these, Ground nut shell ash is one of the good waste materials available from the oil industry. It can be used widely for the replacement of cement. The ground net shell contains CaO, SiO2, Al2O3, and Fe2O3. This experimental investigation was carried out to evaluate the strength of concrete, in which cement was replaced with ground nut shell ash for cubes, cylinders, and Prisms with different percentages which vary from 0% to 30% at an interval of 5% were performed. Concrete was batched by weight on adopting a ratio of 1:2:4 with water–cement ratio of 0.6. Concrete cubes of 150*150*150 mm in dimensions, cylinders of 150*300 mm in dimensions and 100*150 mm prisms are used. These Cubes, cylinders, and prisms were tested for 7, 14 and 28 days for compression, flexural and split tensile strengths. It is observed that 10% replacement of ground nut shell ash shown the highest strength values when compared with other percentages and for 15% replacement of ground nut shell ash the compressive and split tensile strength obtained the highest strength rather than other flexural strength.
