    Abstract: With the increased demand for cement around the world, there is a strong need to find alternatives to cement in concrete. The introduction of a new alternative reduces CO2, a key greenhouse gas. Scientists are conducting research all over the world in order to uncover various material possibilities. River sand is extracted from riverbeds and utilized to build homes and enormous infrastructure to suit population expansion needs. Globalization and modern technology, which are required to fulfill the needs of the global economy both domestically and globally, have become a major concern in the preservation of river sand, which is utilized as a fine aggregate in concrete production. A small trial is carried out in this study to adjust the characteristics of concrete by partially replacing cement with dolomite powder. In this study a small trial is done to modify the properties of concrete by partial replacement of cement with dolomite powder with different percentages 0%,6%,12%,18% and fine aggregate with abaca fiber is varied different percentages of 0%,0.25%,0.5%,1% Different tests are done to determine Compressive and split tensile strength of concrete. All the specimens are used for 28,56 & 90 days and tested for compressive and split tensile strength.

    Abstract: This research looks at using saw dust as a waste material to replace sand and Alccofine (1203) as a partial replacement for cement in concrete to change its qualities. Sand was substituted by weight in the concrete mixes, and the effects of the change on the concrete were examined. The use of saw dust in concrete allows waste (saw dust) to be disposed of while also making concrete lighter in weight. Alccofine (1203) is added as admixture to partial replacement of cement with different percentages of 0%,4%,8%,12%,16% & 20% and sawdust is added as admixture to partial replacement of fine aggregate with different percentages of 3%,6%,9% & 12%.The test results were obtained with reference to compressive and split tensile strength at 7 & 28 days.

    Abstract: Concrete is one of the most widely used construction material in the world. Recent technology has greatly improved the recycling process for waste concrete. Due to the critical shortage of natural aggregate, the availability of demolished concrete for use a recycled concrete aggregate is increasing. The study presents on the natural aggregates and recycled aggregates and also the effect of mineral admixture (metakaolin) on the strength studies. The use of metakaolin in concrete to achieve high strength and durable of concrete. The experimental work on the recycled aggregate and natural aggregates are replaced of 0%,50,100%, replacement of natural aggregate of recycled aggregates were casting in respectively the concrete mixed designed using M30 grade. In the cement partial replacement of metakaolin in 15% used for all mixtures. In the cement partial replacement of metakaolin in 5%,10%, 15%,20% used for all mixtures. The compressive strength of concrete has been determined after 7 & 28 days are curing compared with the results of concrete. The result shows the 15% of metakaolin and 50% recycled aggregates is high strength in concrete. The compressive strength and split tensile strength of the concrete.

    Abstract: Ordinary Portland cement is a major construction material worldwide. Cement manufacturing industry is one of the carbon dioxides emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of greenhouse gases, such as CO2, to the atmosphere. Among the greenhouse gases, CO2 contributes about 65% of global warming. The cement sector accounts for around 7% of worldwide greenhouse gas emissions of the earth’s atmosphere. In order to address environmental effects associated with Portland cement, Alternative binders for concrete production are needed. Low-calcium (Class F) fly ash-based geopolymer from Vijayawada was used in this study. Geopolymer concrete was made with the help of a thermal power plant. The combination of sodium silicate solution and sodium hydroxide solution was used as alkaline solution for fly ash activation. Alkaline solution to fly ash ratio was varied as 0.45. The concentration of sodium hydroxide solution was maintained as 8M, 10M & 12M (Molars). The curing condition of geopolymer concrete was varied as ambient curing. The compressive strength, Split Tensile Strength of the geopolymer concrete was tested at various ages such as 7 and 28days. From the test results it was found that as the alkaline solution to fly ash ratio increases, the strength of geopolymer concrete also increases.

    Abstract: Knowing how long Mars has been around A new planet has been designated as a "sulfur-rich planet." simulation-based building material The development of Martian soil and molten sulfur. in addition to the availability of raw materials for Creating sulfur concrete, while maintaining its strength achieves levels comparable to traditional cementations materials concrete, low temperature, quick curing resistance to acid and salt in the environment,100% recyclability is a desirable feature. The developed Martian Concrete's properties Different sulfur percentages are tested in this study. The best mixing proportions were investigated. To determine strength development, strength variability, and failure mechanisms, three-point bending, unconfined compression, and splitting tests were used 7days 28 days. The results are compared to sulfur concrete made with ordinary sand. The particle size distribution is found to have a significant impact on the final strength of the mixture. Furthermore, because Martian soil is metal-rich, high-temperature mixing produces sulphates and, possibly, polysulfates, which contribute to the high strength. Due to the difference in gravity between Mars and Earth, the optimal mix developed as Martian Concrete has an unconfined compressive strength of above 50 MPa, which corresponds to a roughly 150 MPa concrete on Mars.

    Abstract: It has been determined that quarry dust can be used as a fine aggregate replacement based on the findings of an experimental inquiry. It has been discovered that substituting quarry dust for fine aggregate at 40% yields the best results. Strength then normal concrete and then decreases from 50%. The compressive strength quantified for verifying percentage and grades of concrete for replacement of sand with quarry dust. This present work is an attempt to use Quarry Dust as partial replacement for sand in concrete along with the steel fibers. Attempts have been made to study the properties of concrete and to investigate some properties of quarry dust reinforced with steel fibers; this article presents the compressive and split tensile strengths of hook end steel fiber reinforced concrete with Quarry Dust. In the experimental work natural sand is replaced by Quarry dust in the proportions of 0%, 30%, and 60%. The hook end steel fibers were used in concrete by 0.5%, 0.75% volume fraction. After conduction of experiments on the cube and cylinder specimens, the results showed that, the incorporation of hook end steel fiber reinforced concrete with 30% Quarry dust for M30 grade concrete.
