Materials Used

The need for locally manufactured building materials has been emphasized in many countries of the world because of their easy availability & low cost. Bricks also have been regarded as one of the longest lasting and strongest building materials used throughout history. ordinary building bricks are made of a mixture of clay, which is subjected to various processes, differing according to the nature of the material, the method of manufacture and the character of the finished product. After being properly prepared the clay is formed in moulds to the desired shape, then dried and burnt. on seeing the present day demand for bricks, an attempt was made to study the behavior of bricks manufactured using, different waste materials like Bagasse ash with alumina sulphate, and lime was used to manufacture bricks. The main aim of this project was to compare the compressive strength of the bricks, so for this purpose different percentage of materials were separately added 6%, 8%, 16% & 20% by weight and then the compressive strength of the Bricks was established, and then with the help of graph a comparison between compressive strength of bricks, made out of Bagasse ash with alumina sulphate and normal brick was determined. Before manufacturing the bricks, different properties of the materials (Bagasse ash with alumina sulphate) was also verified. After that bricks were made & sun dried and some bricks were brunt & then with the help v of Compression Testing Machine (C.T.M.) finely their compressive strength was calculated. From this test in this project work it was concluded that the Bagasse ash was that waste material, which gave the acceptable compressive strength. The effects of the addition of Bagasse ash with alumina sulphate by percent-clay mix were also investigated. The admixtures were added in various combinations of proportions by weight (from 6 to 20%). The alumina sulphate, to contribute in attaining denser products with acceptable in compressive strengths, higher softening coefficients, lower water absorption rates, good compaction.

Recycling the waste has been one of the most influential aspect affecting global conditions of the world. In the world of Civil Engineering, it serves the purpose of preservation of the natural building materials such as Sand, Stones, etc. Fair amount of work been done on utilization of the waste such as Fly ash, marble waste, tiles waste, plastic, etc. used as different forms of replacement, provokes the need of work still to be done. So much of the work has been done on wastes available from Marble and Tiles. The combined effect of waste marble powder (M.P) and Ceramic tile waste (CTW) as partial replacement of Cement (10%) and Coarse Aggregates (10%,20%,30% respectively) is to be observed and analyzed. The obtained results will be compared with the conventional cement concrete at 7 and 28 days of Curing. Total 24 number of cylinders casted and tested for their workability and Compressive strength. The Workability of Concrete with replacement decreased with increasing ratio of replacement as well as its Compressive Strength. The Compressive strength of concrete with replacement is approximately of same value as that of Conventional Concrete at (10%+10%) partial substitution ratio.

Cement is one of the most widely used building materials on the planet. Cement manufacturing has also increased carbon emissions to their greatest level in recent years. Alternative or low-emissions binders have become more popular as a partial cement substitute in recent years. Because of its huge yearly output as waste material and low cost, fly ash is now regarded as one of the most accessible choices. Fly ash-based construction materials have a lot of promise as cement substitutes because of their high performance and inexpensive cost. The purpose of this article is to look at how fly ash affects the workability, setting time, compressive strength, and tensile strength of concrete. The kinds and characteristics of fly ash were also investigated.

Management Issues

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%.

Purpose Nano-Clay (NC) is reported as a candidate partial replacement for cement, due to its abundance and relatively low cost - beside reported promotion of different concrete properties. On the other hand, Steel Fibres (SF) has proven to have a positive effect on post fire exposure residual strength of concrete. This paper aims to present the outcomes of a comprehensive research program assessing a hybrid mix between NC and SF in concrete mixtures (NCSF-CRETE). Design/methodology/approach Physical chemical and physical characterization of NC is performed using different tools as XRF spectrometer, and TEM micrograph. Fresh concrete properties of NSCF-CRETE as slump and air content are investigated. Enhancement in permeability using NSCF is verified by comparing its resistance to the penetration of chlorides resistance with regular concrete mix. Besides, the proposed NCSF-CRETE compressive strength is evaluated compared to mixes with NC and SF each used separately at different curing ages. Besides, NSCF and compared mixes are exposed to an indirect fire testing program – two hours exposure – for: 300, 450 and 600°C. Degradation in compressive strength was investigated after exposure to different temperatures and percentage of residual strength is reported. Findings Results indicated an improved performance of NCSF -CRETE of about 40% compared to regular concrete in compressive strength at normal conditions. This improvement extended to its behavior when subjected to indirect fire exposure NSCF also maintained 40% more strength than the residual in regular concrete mix – which suffered severe damage – after 2 h exposure to 600°C. Originality/value Using NCSF-Crete allows retrofitting the structure after exposure to such drastic conditions.

Mine Development

This paper outlines an effective approach to making composite backfill using mine waste material. Composite materials are widely used in many areas of engineering because of their unique structural properties. Cemented rock-tailings are one of the most prevalent materials used for composite backfill because they can effectively make use of mine waste rock and mill tailings that would otherwise be simply considered waste. This backfill method has the capability of maintaining the mine environment while still allowing for continued mine development. An experimental study is being conducted in a cooperative mine research project to investigate the properties of backfill material and specifically the mechanical characteristics of cemented waste rock-tailings fill. This study details the characteristics of the composite backfill aggregate with respect to the compressive strength of the cemented rock-tailings fill and the backfill mix-proportion, as well as outlines a new method of study for cemented rock-tailings fill mechanics. The study results show the compressive strength of cemented rock-tailings fill is dependent mainly on the cement and waste rock content. Ensuring a precise backfill mix proportion can effectively reduce the cement dosage, thereby decreasing the backfill cost realized for the mine.

The construction industry is one of the rapidly growing and the cost analysis suggests that the materials cost is constantly increasing. The continuous extraction of aggregates intensively used in the field is negatively acting to the environment. Therefore research in construction materials should focus not only on discovering new alternative materials but also in appreciating the quality of those locally available for their better application. This research aimed at evaluating the performance of bamboo and mud bricks as two available local building materials, especially with regards not only to their strength but also to new performance concepts which are affordability, energy efficiency and environment friendly aspects. The study comprised mainly of laboratory tests of used materials and cost estimation analysis. Study results established that the considered bamboo and mud bricks, made in ordinary soils and reinforced by sisal fibers were reusable, environment friendly materials and energy efficient, with the bamboo showing the thermal conductivity equal to 0.1496 W/mK. Regarding the compressive strength, reinforced mud bricks with sisal fibers showed an increased value from 1.75 MPA to 4.29MPA, what was in line with related previous studies. The average compressive strength of the studied Arundinaria Alpine bamboo was established at 133,7MPA, while its tensile strength was 88.16MPA and these values were reasonable with comparison to other conventional materials. It is recommended that further research in checking the performance of other types of bamboo as well as about new construction technologies be undertaken in order to enhance the service life of both bamboo and mud bricks.Keywords: Affordability, Bamboo, Conventional concrete, Materials strength, Mud reinforced bricks, Sustainability
