Portland Cement Concrete - an overview ScienceDirect Topics

Portland cement concrete, in particular high strength concrete, is highly susceptible to spalling in a fire [37]. High strength concretes are generally defined as concretes with compressive strengths above 50 MPa, and are widely used in construction since the late 1980s. spalling of high strength concrete, first reported in 1993 [ 37 ], is an ...

Cement - an overview ScienceDirect Topics

In Building Materials in Civil Engineering, 2011. 4.1.2 Hydration and Setting and Hardening of Portland Cement. Mixed with a certain amount of water, cement can turn into the original plastic paste and the plasticity will be lost with the increase of time (but no strength), which is called the initial setting. And the final setting is the moment when the cement begins to have strength.

Concrete Composition - an overview ScienceDirect Topics

In the concrete compositions, 360 kg/m 3 PC-A cement was used; the maximum grain size of the river gravel was 31.5 mm. Because a major objective was to realise highly fluid mixtures, the fresh concrete slumps were 230 plus-minus 40 mm. This resulted in a water to cement ratio of 0.32 for the mixtures containing fillers and 0.35 for the reference mixture (no filler added).

Graham Tailor, in Advanced Concrete Technology, 2003. 11.3.5 Strength. With a high cement content, strengths of 50 MPa are readily achievable, although designers often feel they have to allow for weak bands in the concrete and assume strengths of around 30 MPa in their designs. As noted above, because underwater concrete is not mechanically compacted and there is an excess of water in the

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, (water resistant) such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for ...
