2013-1-1 As we can see, partial cement replacement with dolomite limestone powder results in compression strength increasing. Strength of samples containing 25% of dolomite limestone powder increased by 16.7% and 23.5% at 14 and 28 days age, respectively, in comparison with

2021-2-8 Effect of the dolomite reaction on compressive strength Samples cured at 20 °C showed a lower 3-day compressive strength for PDC than for PLC, regardless of replacement level. This effect might be associated with the lower accelerating effect of dolomite on the early hydration of cement compared to limestone, which produces fewer hydration products of PDC at early ages and thus leads to lower compressive strengths.

2018-7-17 The physical and static mechanical properties of dolomite e.g. density, specific gravity, static compressive strength and elastic modulus values are also determined. Petrological studies of dolomite are carried out through X-ray diffraction (XRD) test and scanning electron microscope (SEM) test. In the SHPB tests, it is observed from the stress ...

2015-6-4 Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

2019-9-23 In all investigated systems, the replacement of CSA cement by dolomite leads to decreasing compressive strength and expansion. However, the mortars containing dolomite and limestone have comparable compressive strength. Moreover, both dolomite and limestone can reduce the strength loss of mortars at 3 days and improve strength development. In the absence of gypsum, a higher expansion can be observed with the replacement by dolomite

(6) uniaxial tensile strengths are usually 10 to 20 times lower than unconfined compressivestrengths. (7) end effects can have a large effect on rock strength. The test specimens must be largeenough to reduce that effect.
