Dec 01 2017nbsp018332Investigations on binary mixes with replacement of cement by RHA first introduced by Mehta in America focused on crucial parameters possibly affect rice husk burning process and enhancement the final product Utility of ordinary Portland cement in high strength RHA concrete to have HPC varies in strength between 70 and 80 MPa.
Aparna KA et al 2015 performed partial replacement of cement and sand using fly ash and pond ash The grade of concrete is M40 cube and beam specimens are casted and cured for 28 and 56 days The 20FA 18PA mix will give a high compressive strength of 4752 Nmm2 for 56 days curing period The 20FA 16PA mix will give a low.
The compressive strength of fly ash concrete at 30 replacement after 28 days is 369 Nmm2 which is lesser than conventional concrete by 681Activated fly ash concrete has higher compressive strength compared to conventional amp fly ash concrete The compressive strength increases by 616 amp 125 higher than CVC amp Fly ash concrete.

Journals On Partial Replacement Of Concrete By Copper Slag And Fly Ash Abstract an experimental investigation was performed to study the effect of fly ash and lime on the strength properties of concrete made by partial replacement of cement with fly ash and limeVarious concrete mixtures were prepared with different proportion of fly ash and lime ranging from 0 for control specimen to 15.
the seashell as a coarse aggregate in concrete along with partial replacement of cement by flyash of 25 Further it was planned to extend the studies into workability characteristics while using seashell as partial replacement This can be effectively used for the improved concrete.
the coconut fibre ash which in turn was used as a pozzolana in partial replacement of cement in concrete production Concrete cubes were produced using various replacement levels of 0 10 30 50 70 and 90 percent of ordinary Portland cement OPC with CFA A total of 50 cubes were.
Results show the more strength of concrete when replacing cement partially by FA than the ordinary concrete Results also show that 10 replacement of cement by FA gives maximum compressive and split tensile strength at 05 1 and 15 addition of PWF Also the replacement of cement by FA increases the workability of concrete.
Nov 01 2019nbsp018332The economic feasibility of the concrete made by partial replacement of cement with FA and copper tailings has been assessed The rate of each material has been taken from the schedule of rates followed in district Gwalior Madhya Pradesh India for the year 2018 detailed in Table A5 of appendix and calculated for each kg of raw materials.
The cement factories produce upto 5 of global artificial CO 2 emission This review paper presents the usage of fly ash by replacement of cement in our general construction In addition review of effect of steel fibers on concrete is also done Keywords Cement flyash class Cflyash class Ffly ash HVFA Green concrete steel fibers.
The replacement of fly ash has don e with 0 5 1 0 and 15 by weight of cement The addition of waste plastic fibers by weight of concrete has been done with 0 05 1 15.
Jul 10 2018nbsp018332In this bamboo leaf Ash is used as partial replacement for cement in ranges of 5 10 15 Strength and durability tests were carried out to assess the feasibility of using bamboo leaf ash as partial replacement of cement in concrete This showed that BLAsh has no significant effect on the density of the concrete comparatively.
Experimental Study on Replacement of Cement by Pond ash and sand by Stone dust Partially In this study Pond ash was used as a mineral ingredient in cement for M20 grade concrete Stone dust are used as additional reinforcement of constant 017 by weight of cement Here Pond ash has been partially replaced with cement at 10 and 20 For.

Partial Replacement of Cement with Wood Ash comparably less fly ash and other residual material A major problem arising from the usage of forest and timber waste product as can be used as cement replacement in concrete Due to current boom in construction industry cement demand has escalated which is the main constituent in concrete.
Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength desired workability and durability as economically value engineered as possible Flyash is the most economical and easily available mineral admixture that can partially replace cement in a concrete mix the resultant concrete.
Fly ash as partial replacement of cement and glass fibers are used as additional reinforcement which satisfies the various structural properties of concrete like compressive split and flexural strength.
Replacing cement partially by GGBS and Fly Ash gives similar strength after 28 daysVarious combinations of concrete gives variable results and maximum quantity of GGBS is 60 that can be replaced by cement and gains the required strength after 28 daysThe use of GGBS and Fly Ash is more cheaper than cement and ecofriendly than conventional.
Concrete is the key component that is usually used in construction as in the world containing 7075 percent of natural rocks sand and 1015 percent of Portland cement Concerns about global sustainability of construction technology and the efficient use of structural aggregates in concrete will help minimize construction problems.
