May 25, 2018 · Research on the reuse of waste materials in the concrete industry has been quite intensive in the past decade. The objective of this research is to identify the performance of ovendried eggshell powder as a partial cement replacement in the production of concrete under both watercured and aircured regimes. Eggshell powder of various amounts, namely 5%, 10%, .
Back in India, a study carried out by the Central Road Research Institute (CRRI) has also shown that copper slag can be used as a partial replacement for sand as fine aggregate in concrete up to 40 per cent in pavement grade concrete without any loss of cohesiveness and the compressive and flexural strength of such.
Aug 20, 2014 · This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of dimensions 1 × 1 m were .
The mechanical properties of special concrete with 30% WBA replacement by weight of natural sand is found to be an optimum usage in concrete in .
In bonded concrete overlays, a new concrete layer is applied to the surface of the existing PCC pavement. This increases the total thickness of the concrete slab, thereby reducing the wheel load stresses and extending the pavement life. The critical requirement for the success of BCO is a good bond between a new and old concrete layers.
Success in discovering alternative material that can function as partial sand replacement for concrete production would reduce the dependency on natural sand supply. This research investigates the effect of POFA as a partial fine aggregate substitute on the workability and compressive strength of palm oil clinker lightweight aggregate concrete.
By replacing 20% of sand by glass waste (powdered), the compressive strength will increase by 21% in 7 days and 25% in 28 days. 2. The glass waste sand be use up to 30% replacement of sand by weight. After that the strength will decrease. 3. Percentage water absorption of concrete will decrease with increase in glass waste. 4.
Mar 17, 2022 · Green concrete is made using industrial waste materials as a partial replacement for other concrete components, like cement or aggregate, whose production takes a heavier toll on the environment. While some forms of green concrete are newer, many may not realize that other types have been in use for decades.
Polypropylene (PP), which is a subset of these plastics, were pelletized and incorporated in concrete hollow blocks as partial replacement for sand. Five batches of specimens, each with 0%, 10%, 20%, 30%, 40% PP replacement (by volume) were molded and cured for 28 days.

Jun 06, 2016 · Partial replacement of sand with quarry dust will make good concrete that is well desired in residential construction. The final product is strong bricks, slabs or tiles that are produced at lower cost compare to using sand.
The processes of producing concrete consume heavily on natural resources such as sand, gravel, water, coal and crushed rock, mining of which damages the environment. It is however possible, that energy and cost efficiency can be achieved by reducing on the amount of clinker, and in its place utilizing partial cement replacements/pozzolans that ...
The mechanical properties of special concrete with 30% WBA replacement by weight of natural sand is found to be an optimum usage in concrete in .
