Fig.1: Air Entrained Concrete. Factors Affecting Air Content of Concrete. Water content; Fine aggregates grading; Coarse aggregates; Temperature of concrete

Factors affecting permeability of concrete: 1) Curing of concrete. Since we have already discussed isolated pores filled with water doesn't encourage permeability. So, during the process of curing, we provide sufficient …

A high amount of water increases the porosity in concrete then the water molecules easily penetrate the concrete and rust the steel bar. In the case of low water content in concrete, it affects the workability of concrete.The recommended water-cement is …

Factors Affecting Workability. Proportions and characteristics of materials and properties of admixtures all have an impact on the workability and other qualities of every concrete mix design; factors affecting workability include:

 — Knowing the factors affecting durability of concrete is the key to define the life span of structures. Let's discuss about the durability of concrete. There are other factors such as concrete class, water-cement ratio, etc that need to …

 — When working with concrete, there are numerous factors that affect the overall strength of the finished material. To produce the desired strength for fresh concrete, all these factors must be taken into consideration, as they all play an integral role within the setting and formation of the product.

Factors Affecting Concrete's Strength. The strength of concrete can be affected by various factors, including: Water Cement Ratio. The water-to-cement ratio is a critical factor that affects both the strength and workability of concrete. A higher water-to-cement ratio generally results in higher workability but lower strength.

 — Factors affecting the concrete setting time. Different factors can affect the setting times. This can be, for example, water/cement ratio, temperature conditions, and admixtures. Water/Cement ratio The …

Factors Affecting Concrete Longevity. Before diving into examples, it's important to understand the factors that influence how long concrete lasts: Environmental Exposure: Concrete structures in harsh weather conditions or corrosive environments (like saltwater exposure) tend to have shorter lifespans.

 — Creep may affect structural behavior by violating service limit states, redistributing stress or losing prestress forces. For that, knowing the significance of factors that influence creep is a ...

By Er. Kaushal Kishore, Materials Engineer, Roorkee Concrete Strength Cement like water, aggregates and some times admixtures is one of the ingredient of concrete. The mixing of these materials in specified proportions produces concrete. Accordingly cement alone is not a building material, it is the concrete which is a building material. For a given...

Factors Affecting Concrete Mix Design Strength The above stated design strength variable factors are explained below based on different theories and specifications. 1. Water/cement ratio Water to cement ratio (W/C ratio) is the single most important factor governing the strength and durability of concrete. Strength of concrete depends upon W/C ...

Concrete permeability significantly influences its durability by affecting its susceptibility to water penetration and subsequent damage. Maintaining a low water-cement ratio and incorporating pozzolanic materials are effective strategies for reducing permeability and …

 — What Factors Affect Concrete Setting Time? Several factors influence the setting time of concrete: Mix Proportions: The ratio of cement, water, and aggregates affects how quickly the concrete sets. Type of Cement: Different types of cement have varying setting times. For example, Portland cement sets faster than other types.

 — When the concrete is loaded in compression, an elastic strain develops as shown in figure A. If this load remains on the member, creep strain developed with time.The main factors affecting creep strain are the concrete strength and mixture, the type of aggregate, curing, the relative humidity and the duration of the sustained loading.

Factors affecting Creep of Concrete: 1) Quality of aggregate: Aggregate has an extremely low creep rate. The aggregate has a restraining impact on the magnitude of creep, which influences the creep of concrete. The paste that creeps under load is restrained by non-creeping aggregate. The greater the aggregate strength, the greater the ...
