14/9/2018 Any experienced construction worker will understand that there is a very fragile relationship between the water to cement ratio in concrete. Sure, there is also a delicate relationship between all concrete ingredients including additives and aggregate, but the water to cement ratio needs to be precise to ensure the finished product ...

2021-6-10 From the Table 4 we could infer the different slump values at different aggregate-cement ratios. As the A/C ratio increases due to lack of concentration of cement paste relative to aggregate slump value increases. Its value ranges from 155mm to 163 mm as A/C ratio varies from 4.5:1 to 6.5:1.

2013-6-9 Cement clinker and finished cement are traded internationally. Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2). The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide. Generally around 0.5 tonnes

We believe factors like how compact the cement is in the box matters. Several factors play with the overall strength of the concrete (aggregate’s quality, w/c ratio, curing etc.).

Cement is known as the world’s second most consumed substance after water. It is produced from limestone, shell, and clay and processed in a heated temperature of more than 1000 degree Celsius. Cement is the main ingredient in construction. Without cement, concrete construction of infrastructure is impossible (Selim Salem, 2010).

2019-2-8 The overall national ratio decreased uniformly from 72.4% in 2002 to 53.7% in 2016 with an average value of 65.0%. A higher ratio indicates a larger clinker production and a smaller cement production, whereas a smaller ratio indicates a smaller clinker production but a larger cement production.

2017-12-16 strength is chiefly influenced by w/c (water-to-cement ratio, mass basis). But, even for a given w/c, substantial variations in concrete strength may be observed based on the characteristics of constituent materials; e.g., cement type, the type of aggregate used, the paste content, mineral and chemical admixtures, etc. [1,2]. Therefore, a

A minimum amount of water, approximately 25% of the weight of the cement, must be included to chemically hydrate the concrete batch. In the actual mixing process, though, it takes about 35% to 40% water to work through the mixing process, get to the actual cement, and cause effective hydration.

2014-9-23 Cement production is associated with a considerable environmental load, which needs to be fully understood before effective measures can be taken. The existing literature did not give detailed life cycle assessment (LCA) study of China and had limited potential for investigating how best available techniques (BATs) would provide a maximum benefit when they are applied in China.
