“…Figure 3 shows the relationship between w/b ratio and f cm,28 for each of the four limepozzolan concretes in comparison to corresponding results for the two reference CEMI-concretes.  For fully compacted CEMI concretes compressive strength is has been shown to be related to w/b ratio as defined by Abrams law (see equation 1) [37].…”

“… Determine the W/C in concrete mixtures: Based on the Abrams’ law (Cf. Equation (5)) [ 28 , 29 ], the W/C can be determined with a given target strength grade (cubic compression strength was proposed in the current study). Determine the SP dosage: The proper dosage of SP can be acquired by a few batches of trial to meet the required flowability (other fresh properties related to workability including segregation test, filling test, and passing test, etc.…”

The current study aims at proposing a novel and simple method for designing fluid concrete such as self-compacting concrete (SCC) with a low cementitious binder content to reduce the carbon footprint. Different testing methods regarding the packing density of aggregate mixtures are performed and compared. The W/C was determined according to the target compression strength. Slump flow spread is carried out to determine the most appropriate superplasticizer (SP) dosage and aggregate volume fractions and proportions in concrete mixtures. Furthermore, hardened performance, including compression strength and drying shrinkage of the fluid concrete, are characterized. Finally, a mix design process of fluid concrete with low cement content was proposed based on the preferred fresh and hardened properties of the concrete mixtures.

“…Watercement-density ratio law has a good simulation with R-square of 0.9776. It also seemed that while water-cement ratio is higher than 0.3, the simulations are better because Abrams' law is valid over the range of water-cement ratios of 0.30 to 1.20 [19,20]. For low water-cement ratio, prediction of compressive strength is more complicated.…”

In the present contribution, the water-cement-density ratio law for the standard curing 28-day compressive strength of cement-based materials including grout, normal concrete, ceramsite concrete, and foamed concrete is proposed. The standard curing 28-day compressive strength of different grouts, normal concrete, ceramsite concrete, and foamed concrete was tested. Simulations for Abrams’ law, Bolomey’s formula, and water-cement-density ratio law were carried out and compared. The water-cement-density ratio law illustrates better simulations for the prediction of the 28-day compressive strength of cement-based materials. The water-cement-density ratio law includes both the water-cement ratio and relative apparent density of the cement-based material. Relative apparent density of the cement-based material is an important one of all the factors determining the compressive strength of the cement-based material. The water-cement-density ratio law will be beneficial for the precise and generalized prediction of the 28-day standard curing compressive strength of cement-based materials.
