In general, lower water–cement ratios produce stronger, more durable PCC. If natural pozzolans are used in the mix (such as fly ash), then the ratio becomes a water-cementitious material ratio (cementitious material = portland cement + pozzolonic material).

The article aims to answer the question "What is PCC concrete?". It will also discuss the purpose, uses, and making of PCC concrete. ... As a result, lean concrete has a lower cement-to-water content ratio than normal cement concrete. The term "lean concrete" refers to concrete containing less than 10% cement by weight. Leaner …
PCC shuttering should be of the exact size and thickness; Water should be mixed with a bucket, in a measured quantity, as per w/c (water/ …
Given data: The grade of PCC = M10. Length of the PCC bed = 4m. Breadth of the PCC = 2.5m. The thickness of the PCC = 100mm. = 0.01m. The volume of the PCC bed = length × breadth × thickness = 4m. × 2.5m. × 0.01m. = 1 CUM. Here, Cement:sand: aggregates = 1:3:6 (a:b:c) M10 grade means 👉 1:3:6 ratio. Wet volume of PCC = 1 cum.
Assume concrete ratio is 1:2:4. Where 1 signifies the ratio of cement, 2 signify the ratio of sand (fine aggregate) and 4 for coarse aggregate (crushed stone). Dry volume = wet volume x 1.54. Determine crushed …
The ratio of materials in PCC: The ratio of cement, sand, and brick chips in the foundation should be 1:3:6.But if it is applied in the car parking area, the ratio will be changed to 1:2:4. Properties of plain cement concrete. …
Uses of Different Grades of Concrete 1. Ordinary Grade: M5, M10, and M15 grades of concrete are mostly used in Plain Cement Concrete (PCC) works as bed concrete below column footing. While …
To obtain the desired water-cement ratio, the complete amount of water for mixing must be added before 25% of the mixing period has passed. ... PCC concrete: Factors that influence the method of …

The main difference between lean mix concrete and PCC concrete is that lean mix concrete contains lea amount of cement as compared to water content which is present in it. This means, when compared to plain cement concrete, the ratio of cement to water has smaller in lean mix concrete.
The water-cement ratio is a convenient measurement whose value is well correlated with PCC strength and durability. In general, lower water-cement ratios produce stronger, more durable PCC.
Water-cement ratio. The strength of PCC is most directly related to its capillary porosity. The capillary porosity of a properly compacted PCC is determined by its water-cement ratio (Mindess and Young, 1981 [2]). Thus, the water-cement ratio is an easily measurable PCC property that gives a good estimate of capillary porosity and thus, strength.
For M 15 grade of concrete mix, the ratio is 1:2:4, which means 1 part cement, 2 part sand, and 4 part aggregate used to prepare concrete mix with water. If you are using M 20 grade of concrete then you have to …

Poisson's ratio is defined as the ratio of transverse to longitudinal strains of a loaded specimen. This concept is illustrated in Figure 1. In realistic terms, Poisson's ratio can vary from initially 0 to about 0.5 (assuming no specimen volume change after loading).
How do you calculate PCC? Suppose we have project of making concrete pavement of area 100m2 and slab thickness of PCC is 150 mm.
