2020-5-22 Tricalcium silicate (c3s) :-. Tricalcium of cement is responsible for early strength of concrete. First 7 days strength is due to tricalcium amount in cement. Tricalcium of cement produce more heat of hydration. A cement with more tricalcium silicate content is better for cold weather concreting. 2.
2019-9-14 Portland cement concrete is a mixture of Portland cement, water, coarse and fine aggregates, and admixtures proportioned to form a plastic mass capable of being cast, placed, or molded into forms that will harden to a solid mass. The desirable properties of plastic concrete are that it be workable, placeable, and non-segregating and that is set at the desired time.
2011-4-20 Concrete Association and in that capacity chaired the committee that produced ‘Guidance to the Engineering Properties of Concrete’ from which this publication has developed. Properties of Concrete for use in Eurocode 2 How to optimise the engineering properties of concrete in design to Eurocode 2 A cement and concrete industry publication
【Abstract】 Blended cement using supplemental cementitious materials such as fly ash and blast-furnace slag,which leads to reduction of CO_2 emission in the process of cement production,has been extensively used in many countries.However,in Japan,the consumption of blended cement accounts for only 20%.Especially,use of fly ash cement for concrete structures is rare except for dam concrete

From the point of view of the fly ash quantity and concrete properties ratio, the obtained concrete with 20% volume of cement replaced by fly ash showed the optimum results. View full-text Article
2020-4-3 Despite this porosity, cement possesses excellent strength and binding properties. Of course, by decreasing this porosity, one can create a denser and even stronger final product. Starting in the 1980s, engineers designed a material — high-performance concrete (HPC) — that did just that.
2017-5-9 The transition process of changing of concrete from plastic state to hardened state. Setting of concrete is based or related to the setting of cement paste. Thus cement properties greatly affect the setting time. Factors affecting setting: Following are the factors that affect the setting of concrete
2019-9-14 Portland cement concrete is a mixture of Portland cement, water, coarse and fine aggregates, and admixtures proportioned to form a plastic mass capable of being cast, placed, or molded into forms that will harden to a solid mass. The desirable properties of plastic concrete are that it be workable, placeable, and non-segregating and that is set at the desired time.
2021-8-6 Properties of Fresh Concrete. 1. Workability of Concrete. The ability to handle and place the concrete and compact without segregation and bleeding is called the workability of concrete. The workability of concrete depends on the quality of material, proper mixing, and water-cement
2017-3-19 No segregation of cement paste from aggregates (especially coarse ones) Fluidity & compactability known as workability. Higher workability concretes are easier to place and handle but obtaining higher workability by increasing water content decreases strength and durability. Properties of Concrete. Following are the important properties
2021-8-5 Plain cement concrete (PCC)-Materials, Properties, and Mixing Plain cement concrete (PCC) is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportions. It does not contain a steel rod. If steel is kept in the concrete then it is called Reinforced cement concrete
2021-8-12 Rapid urbanization and ‘concretization’ have increased the use of concrete as the preferred building material. However, the production of cement and other concrete-related activities, contribute significantly to both the carbon dioxide emissions and climate change.
