The former is described as compact and powerful, able to cut rock with unconfined compressive strengths
of up to 50 megapascals (MPa).
Though this, the compressive strength
re suits were obtained and intermediate binder contents are estimated for certain compressive strengths
The compressive strengths
of recycled concrete with aggregate groups A, B, and C were lower than that of control concrete by 2.3~8.7MPa.
Caption: Figure 6: The compressive strengths
of concrete grade 20 MPa.
From Figure 2, it can be seen that the compressive strengths
of the water-cement ratios of the H2 and H3 cement blocks are increasing with time.
According to Table 3, at 20 [degrees]C, the OPC mortar (Z0) achieved a compressive strength
of 53.48 MPa while the compressive strengths
of the mortars containing zeolite ranged from 39.91 MPa to 54.74 MPa.
Seven-, 14- and 28-day breaks on Fusion-derived specimens recorded compressive strengths
of 4,350 psi, 4,580 psi and 5,460 psi.
To compare with the strength results, the existence of CNTs' agglomerations in these batches did not affect their flexural and compressive strengths
, which were higher than those of lower CNTs' contents of 0.03 and 0.08%, as well as the plain cement batches.
Testing of Compressive Strength
. In order to reveal the effect of oxidation on the mechanical properties of MG, the compressive strengths
of the specimens oxidized at two typical temperatures were tested.
Results: Maximum and minimum compressive strengths
were observed in ZC7 (344.14+-19.22) and LC1 (202.80+-15.52) groups.
Figure 6a shows that the compressive strengths
of the cement-carbide waste specimen at one day range from 0.38 to 1.15 MPa while that of OPC specimen was 1.19 MPa.
As shown in the previous tables, the compressive strengths
for 7 days curing time for cement dosages 200, 400 and 600 kg [m.sup.-3] are respectively 1.2 MPa (sd = 0.1 MPa, cv = 11.2%); 1.5 MPa (sd = 0.1MPa, cv = 4%) and 2.05 MPa (sd = 0.31 MPa, cv = 15%).
