concrete compressive strength, axial deformations, and loading Civil Eng Res J 6(2): CERJ.MS.ID.555685 (2018) 0064 Abstract The aim of this paper is to develop a 3D non-linear finite element model to simulate the behavior of Concrete-Filled Steel Tubes (CFSTs) under compressive loading. The FE model was developed using the commercial software

Compression test on concrete is carried out using compression testing machine. For compression test of concrete cube specimens of 150 mm X 150 mm X 150 mm are used. These specimens are tested by compression testing machine after 7 days curing or 28 days curing. Compressive strength =

properties, compressive strength and hardness are noticeable as the wt % of the glass powder increases. The microstructures of Finally, the chapter presents suggestions for further studies on recycled glass concrete, and proposes future trends of using recycled glass in concrete in more economic and eco-efficient ways

M15 Grade concrete cylinders of diameter 150mm X height 300mm of 48 numbers were cast to study compressive strength and split tensile strength. Out of 48 cylinders 24 numbers were without flyash and the remaining was with flyash. The cylinders of 24 numbers were divided in to 2 sets, as 12 in each set. 1st set is for compressive strength test

Sample 1: 18% fly ash and 82% cement Sample 2:20% fly ash and 80% cement

Alccofine was varied in percentages of 0, 5, 10 and 15%, Silica fume was varied in percentages of 0, 5, 10, 15 % The aim of the investigation was to see the effect of alccofine on compressive strength of concrete and do a comparison on 7, and 28 days strength.The results showed that the cement replacement by 10% of alccofine gives higher values

using of E-waste in replacement of coarse aggregate give the different result. Till 12% replacement of aggregate with E-waste the compressive strength was better than reference concrete. At 20% replacement of E-waste the strength reduces in higher range E-waste in concrete replaced the coarse aggregate 0% -20%.

from concrete with 24 MPa compressive strength. For the same size of recycled aggregate, the attached mortar fraction increased to 36.7% and 38.4% when the recycled aggregate was produced by crushing concretes with compressive strengths of 41 MPa and 51 MPa, respectively. According to Japanese studies [8], approxi-

concrete compressive and tensile strength and E-waste. It was discovered that substituting 20% E-Waste for standard geopolymer concrete of M40 grade resulted in a higher intensity. Mahaboob Basha et. al. [8], have studied the effect of E-waste and M-sand as a

Compressive Strength Fibres do little to enhance the static compressive strength of concrete, with increases in strength ranging from essentially nil to perhaps 25%. Even in members which contain conventional reinforcement in addition to the steel fibres, the fibres have little effect on compressive strength.

recently, compressive strengths approaching 138N have been used in cast-in-place buildings. The advent of pre stressed concrete technology has given impetus for making concrete of high strength. In India high strength concrete is used in pre stressed concrete bridges of strength from 35 MPa to 45 MPa.

However, the specific compressive strength (strength to density ratio) increased with increasing amounts of plastic aggregate, which is a good standpoint for recycling this waste if specific applications are identified that can accept the technical limits of this material while using the positive parameters that could be useful for the application.

Abstract: The objective of this Research investigation was to study the compressive strength behavior of Steel Fibre Reinforced Concrete (SFRC) using Round straight fibres with aspect ratio of 75 .Specimens were cast without fibres and with fibres of 0.5%, 1%, 1.5% and 2 %. Compressive strength test were conducted on cube. A

Moreover, the synthetic rubber pads cannot be used in concrete cylinder with strength greater than 80MPa according to ASTM C 1231-00. New 'sand-capping method' presented in this study, can be applicable to the compressive strength evaluation of the high strength concrete in the range of 70~100MPa.

Concrete compressive strength at 28 daysfc' value for all mixtures are listed in Table 3. Based on Table 3, the compressive strength of concrete for M0.5 and Ml and Ml .5 is higher than compressive strength of specimen MO. On the other hand, as the fiber content got higher in M2, concrete compressive strength becomes less than MO.

Abstract: In this study, compressive stress-strain behavior and microstructure of polypropylene fiber reinforced concrete (PFRC) were investigated. Four fiber volume fractions of 0.05%, 0.10%, 0.15% and 0.20%, and three fiber aspect ratios of 167, 280 and 396 were selected as the main variations. The failure pattern, compressive strength,

After 3, 7 and 28 age curing of cube specimen, the compressive intensity was found. Similarly the 7 and 28 age tensile strength, young’s modulas, modulus of rupture be calculated by casting cylinders and prisms. The best possible quantity E-waste be added to retain the target mean strength

Testing of compressive strength up to 90 days and drying shrinkage up to 3 years maturity was undertaken using standard mortars of a 0.5 water-to-binder ratio and also with a water addition sufficient to produce equal workability to the standard mortar.

It has been found that the compressive strength of concrete replacing e-waste is high compared to conventional concrete with 10% of replacement, flexural strength is high compared to conventional concrete with 10% of replacement and the split tensile test is high compared to conventional concrete with 12.5% replacement.

In this investigation, a feasibility study is made to use Rice Husk Ash as an admixture to an already replaced Cement with fly ash (Portland Pozzolana Cement) in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive and Flexural).

The purpose of this experiment is to analyze the steady state condition in a concrete slab. Temperature measurements were made for each scenario and were used along with physical dimensions to compute various heat transfer parameters. In this paper, the investigation was made by the partial replacement in the coarse aggregate with E-waste (PCB cutting waste) (FR-4) in the conventional concrete.

The rule of 85% can be best explained by ASTM C42-04 Section 3.5 " There is no universal relationship between the compressive strength of a core and the corresponding compressive strength of standard-cured molded cylinders. The relationship is affected by many factors such as the strength level of the concrete, the in-place temperature and

Compressive strengths for different ages of geopolymer concrete . From the Table 2, it can be observed that the compressive strength of geo-polymer concrete increases enormously with increase in percentage of slag (GGBS) to flyash. The strength is varying significantly in line with conventional concrete with increase in age of concrete. Table 3
