Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states. Moreover, concrete mixes are designed in order to achieve a defined workability, strength and durability . Finally, this article presents factors affecting the ...

Feb 15, 2021 Concrete is a heterogeneous, brittle and the most widely used construction material. Factors governing the strength of concrete are many and are discussed below. Watercement ratio In 1918 AD Duff Abram made some experiments with tweaking the amount of water added to mix the concrete.

The tensile strength largely depends on the reinforced steel used in the concrete, however, the concrete itself has also a partial role in creating the tensile strength. In this article were are discussing in detail, the factors of compressive strength of the concrete material. Factors affecting the Compressive Strength of the concrete

Date 211972. Abstract An investigation was made of the effects of steel fiber parameters and concrete mix parameters on the flexural strength properties of steel fibrous concretes and mortars. Compositions were evaluated in which the steel fiber content was as high as 4.0 volume percent. Data are presented which show the relationship of ...

Key Factors Affecting Strength of Concrete. 2. Water Cement Ratio. The water-cement ratio is one of the most important factors affecting strength of concrete. Depending on the water-cement ... 3. Air Entrainment. 4. Aggregate Proportion. 5. Ratio of Aggregate to Cement. 6. Curing Period.

Jan 29, 2015 Factors Affecting Concrete Mix Design Strength. 1. Watercement ratio. Water to cement ratio WC ratio is the single most important factor governing the strength and durability of concrete. 2. Cement content. 3. Relative Proportion of Fine amp Coarse Aggregates. 4. Admixtures.

Strength and workability are both dominating factors in the making of concrete. Strength can be increased by increasing cement content but this in fact reduces the workability. Moreover,the water content can be increased for better workability, but this affects the strength.

Factors Affecting the Strength of Concrete Generally following factors affect the strength of concrete. Here these factors are discussed in brief 1. Type of cement. 2. Type of aggregate . 3. Richness of the mix . 4. Curing temperature . 5. Age of concrete . 6. Effect of compaction . 7. Aggregate-Cement ratio . 8. Temperature at the time of ...

Jan 01, 1985 Many factors are known to affect the strength and creep properties of laterized concrete prisms. Those considered in this report include mix proportion, watercement ratio, curing ages, grain size ranges, stress level, lateritic soils-river sand variation. Moulds of 50 50 250 mm high were used for making prism specimens.

Jun 12, 2018 The mean compressive strength that is required at a specific age usually 28 days, will determine the nominal water-cement ratio of the mix. The other factor affecting the strength of the concrete at a given age and cured at a prescribed temperature is the degree of compaction.

been paid to study the parameters affecting the exural tensile strength of concrete. The effect of the factors like age and con-nement of concrete on exural strength has not been investi-gated properly and proper inter-dependency of various factors that affect the exural strength

Many factors are known to affect the strength and creep properties of laterized concrete prisms. Those considered in this report include mix proportion, watercement ratio, curing ages, grain size ranges, stress level, lateritic soils-river sand variation. Moulds of 50 50 250 mm high were used for making prism specimens.

Jul 21, 2020 There are several factors affecting the ready-mix concrete price, which is why these parameters are critical to analyse comprehensively. Furthermore, the role of ready-mix concrete is a crucial one as it is a highly customized building material that is designed to meet the specific requirements of each project.

Many factors have been shown to influence the flexural tensile strength of concrete, particularly the level of stress, size, age and confinement to concrete flexure member etc. The concrete ...

Nov 17, 2018 Factors that Affect the Strength of Concrete. 01. WaterCement Ratio. The ratio of the weight of water to the weight of cement is called WaterCement ratio. It is the most important factor for gaining the strength of concrete. The lower wc ratio leads the higher strength of concrete.

Mar 11, 2020 Factors affecting concrete mix design. Strength and durability of the concrete mix design are dependent upon the following factors Grade designation Concretes strength is measured in Nmm2 when subject to test after curing in any curing medium. The choice of concrete grade depends on its usage. Choice of cement Cement choice varies ...

Mechanization of construction will affect jain, 2002 project cost, as capital investment is assumed to Ready mix concrete production was commercially become higher. So, to get maximum performance amp introduced in 1993 in India. 15 of total production of minimum operation cost of machinery machineries concrete is ready mix concrete.

Workability of concrete is measured in terms of the ease of mixing and placing of concrete. Highly workable concrete can easily be mixed, placed and transported. All the materials and processes involved in producing concrete affect the workability of concrete. Factors Affecting the Workability of Concrete

Feb 05, 2020 Factors Affecting Concrete Mix Design. ... Not taking this step may result in a less than desirable output and will also affect the final strength of the structure. Having said that, lets take a look at some of the determining factors for a concrete mix design 1. Cement Choice.

Nov 08, 2018 The present contribution ha s highlighted the key fact ors affecting the compressive strength of foamed. concrete, at least in the low-to-medium density rang e explor ed in this experimental cam ...

The water-cement ratio is the first parameter we used when starting to work out the concrete mix design. This the dominant amongst all other factors affecting concrete mix design. The lower the water-cement ratio, the higher the strength of the concrete as the cement content increase compared to water content.
