Jun 04 2015 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. C 0 can be estimated from porosity or sonic velocities but
Abstract The purpose of this work is to describe the effect of fine ground dolomite limestone on important physic and mechanical properties of concrete. The present examinations indicate that the use of dolomite limestone as component instead of limestone is a viable solution for producing Portland dolomite limestone cement especially for quarries with dolomitic inclusions or overburden.
Rocks are rated on the on the Mohs Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Quartzite is 6-7 whereas its compressive strength is 115.00 Nmm 2. Streak is the color of rock when it is crushed or powdered.
Feb 20 2021 Natural crushed dolomite with a specific gravity of 2.65 and a particle size range of 4.75–12.5 mm was used as a coarse aggregate in all mixtures while a fine aggregate of natural sand with a specific gravity of 2.5 was used in all concrete mixtures. . Compressive strength. The results of compressive strength tests are shown in Figure 4 .

May 18 2018 Compressive strength of Concrete Formula The Compressive strength of specimen can be calculated by dividing maximum load carried by the specimen by cross-sectional area of the specimen cubes. The surface area of specimen 150 x 150 22500mm 225cm . Assume The Max compression load is 450KN.
Dec 30 2017 For the samples containing dolomite the maximum compressive strength was achieved by 5wt addition after 28 days and for 10wt addition after 90 days of hydration. Moreover at lower replacement levels samples containing dolomite showed a lower compressive strength than samples containing limestone.

The compressive strength and split tensile strength of the replaced concrete will be compared with the conventional concrete at 7days 14days and 28days. The optimum replacement percentage of dolomite and vermiculite is 15 percentage and 20 percentage respectively. Keywords- Dolomite; Vermiculite; Compressive strength; Split
compressive strength is computed after 7 14 amp; 28 days curing. At 30 replacement the compressive strength is found to be higher than the remaining proportions. Hence maintaining 30 of quarry dust dolomite powder is incorporated to replace cement at 0 10 20 30 40 amp; 50 respectively.
