by dolomite silica by 50% and cement is replacement by fly ash by 30% the compressive strength increased by % than conventional concrete and split tensile strength results indicate that 24% increase in strength is achieved and flexural strength also improved % then conventional concrete.

Note 1: The tensile strength of rock determined by tests other than the straight pull test is designated as the "indirect" tensile strength and, specifically, the value obtained in Section 9 of this test is termed the "splitting" tensile strength.

Yield strength of a solid may be defined as the maximum stress difference at the beginning of large deformation by plastic flow. This definition is arbitrary, and does not account for time effects. The yield strength varies from 10 to 1,000 kg/cm^, depending on the exper­ imental conditions.

Deepthi [8] had studied the compressive strength of concrete with dolomite powder and crushed tiles. Her study aim is to create a better concrete in low cost and is focused on the compressive strength of the concrete by partially replacing cement with dolomite powder and coarse aggregates with crushed tiles. In first phase the

Sedimentary > Carbonate > Dolostone light to mediumgray thickbedded coarsely crystalline dolomite.

Nine rock types including Sandstone, Limestone, Siltstone, Dolomite and Marl collected from six different rock formations of the Salt Range area of Pakistan were tested to evaluate the correlations between the uniaxial compressive strength and the corresponding values of the point load index.

Compressive strength: The compressive strength of cement is determined by compressive strength test on mortar cubes compacted by means of a standard vibration machine. Local sand is used for the preparation of cement mortar. The specimen is in the form of cubes mm× mm × mm [14].

The maximum compressive strength obtained has been for a mix prepared with 25 percentage replacement of cement with fly ash and dolomite powder ( percent fly ash and percent dolomite powder). This mix has been taken as the optimized mix.

Table strength 7 day 7 day and 28 day compressive strength of the specimens containing 5%, 10%, 15% and 20% dolomite replacing cement are shown in the Table, M7, M8 and M9indicates the mixes containing 5%, 10%, 15%, and 20% of dolomite

compressive strength of the cement remarkably. Water tightness of Sorel's cement increases with the increase in quantities of the additive (15%, 20%).

or dolomite, pellets hardened compressive strength increases with increasing addition of up to % for lime, dolomite respectively for 3 to, regardless of the addition of bentonite and water over these limits compressive strength decreases with increasing margins; regardless of the addition of flux and water

Correlation between Uniaxial Compressive Strength and Point Load Index for SaltRange Rocks Nine rock types including Sandstone, Limestone, Siltstone, Dolomite and Marl collected from six different rock formations of the Salt Range area of Pakistan were tested to evaluate the correlations between the uniaxial compressive strength and the corresponding values of the point load index.

dry compressive strength and dry shear strength respectively. Dry compressive and shear strength tests are important because refractory linings undergo different stresses from the materials being worked upon in the furnace. So there is need to test and find out whether the material can withstand such loads without failure during use.
