Effect of Quarry Waste on SelfCompacting Concrete Containing ... Hindawi
This paper presents the results of the experimental work conducted to study the effect of quarry waste on selfcompacting concrete containing binary cementitious blends of fly ash and cement. For this purpose nine trial mixes were prepared, where the percentage replacement of river sand by quarry waste was 0%, 10%, 20%, 30%, 40%, 50%, 70%, and 100% to study the flowability ...
Placement and Design of Concrete in Drilled Shaft Construction: Part 2
However, it is more expensive than fly ash or slag cement. Both fly ash and silica fume tend to reduce the amount of bleeding experienced by the concrete. Fly ash, silica fume and slag cement will all have an effect on the rate of strength and stiffness development in drilled shaft concrete, with slower strength development for flay ash or slag ...
Performance of fly ash based geopolymer concrete with partial ...
because fly ash contains sio2, al2o3, p2o3, and fe2o3 which are quite high, so fly ash is considered capable of replacing cement study aims to obtain geopolymer concrete which has the best workability so that it is easy to work on (workable geopolymer concrete / self compacting geopolymer concrete) and obtain the basic .
Influence of Aggregate Type and Size on Ductility and Mechanical ...
containing either crushed dolomitic limestone sand or gravel sand with maximum sizes of or mm ( or in.) were investigated. For each aggregate type and maximum aggregate size, three different ECC mixtures with fly ash/portland cement (FA/C) ratios of,, and were cast. Specifically, the effects
Experimental Study On Partial Replacement Of Cement With Fly Ash And ...
Fly Ash (FA) and fine aggregate by quarry sand with using admixture in huge quantity of concrete is consumed by construction industry all over the world. In India, the conventional concrete is produced using natural sand from river beds as fine aggregate.
Lowcalcium fly ashbased geopolymer concrete: Long term properties, (2006)
The compressive, tensile flexural strength of Geopolymer concrete have been studied and compared with is one of the cheapest abundantly available fibers. Glass fiber has been extensively used in reinforced cement. Glass fibers were added to the mix in fractions of %, 1%,% and 2% to the weight of cement.
Comparative Study on Conventional Concrete and FlyAsh ... IJERT
In conventional concrete, weight of concrete is one of the parameters to compare with weight of fly ash aggregate concrete. Normally density of concrete is in the order of 2200 to 2600 kg/ heavy selfweight makes it as uneconomical structural material compared to low selfweight of fly ash aggregate concrete.
Water Absorption and Compressive Strength of SelfCompacting Concrete ...
Five mixes with different percentages of quarry dust (0%, 10%, 20%, 30%, and 40%) as partial replacement for sand and a constant 10% of fly ash as partial replacement for cement is considered. The test results for water absorption and compressive strength were carried out after 7 days and 28 days of curing.
Properties of I Shaped Paver Blocks Using fly Ash Based Geopolymer Concrete
or other substances that may be deleterious to concrete is used. Extra water is added to improve the workability and the amount of water added is 10% by weight of binder materials (fly ash and GGBS). Table 1: Chemical composition of fly ash Oxides Requirements as per IS (% by Mass) Test result (% by Mass) 1. SiO +Al 2 2 O 3 +Fe 2 O
Irjet Experimental Investigation on Utilization of Waste Plastic ...
In this study, the use of the fly ash and paper pulp as replacement for Cement and the coarse 20 mm aggregate is replaced with the plastic waste at various percentages and the quarry dust is completely replaced with the sand to create a sustainable, ecofriendly and light weight concrete and study of different properties has been carried out. 2.
project report of sand replacement by fly ash
Lots of research has been carried out for effective utilization of fly ash in ... ash can be used as fine aggregates in concrete by partial replacement of sand. As per M60 Mix Design in this project we will replace the alccofine and fine fly ash partially with cement and pond fly .... results of 7,28 days cube 28days beam.
Green Concrete: Efficient Ecofriendly Construction Materials
requirement and improving the paste flow behavior. Refer Table 1 for the Chemical Properties of Fly Ash. FLY ASH AGGREGATES Several lightweight concrete aggregates can be produced from fly ash. In addition to the use of furnace bottom ash in concrete masonry, pellets of fly ash can be bound by thermal fusion or chemically, using cement or lime.
Partial Replacement of Sand with Quarry Dust in Concrete Semantic Scholar
Effect of Quarry Dust and Fly Ash Mix on strength properties of M40 grade Concrete. Anjali H Jamale, U. R. Kawade. 2015. this paper presents the variation in the strength of concrete when replacing sand by quarry dust and also effect of inclusion of Fly Ash with the addition Quarry Dust. Slump cone test, carried out on..
Influence of Aggregate Type and Size on Ductility and Mechanical ...
containing either crushed dolomitic limestone sand or gravel sand with maximum sizes of or mm ( or in.) were investigated. For each aggregate type and maximum aggregate size, three different ECC mixtures with fly ash/portland cement (FA/C) ratios of,, and were cast. Specifically, the effects
Properties of Banana Fibre Reinforced Fly Ash Concrete Ijmter
specific gravity of the fly ash was, which was less than that obtained for cement. The loose bulk density and cocompacted bulk density of the fly ash were 1300 and 1418kg/m3 respectively. The chemical composition of the fly ash is presented in Table 2. The result shows that the combined SiO 2, Al 2 O 3 and Fe 2 O 3
