The addition of dolomite and limestone to calcined-clay containing Portland composite cement affects not only the phase assemblages in a similar way but also the compressive strength development The addition of dolomite increased the compressive strength up to a replacement level of 10%wt This effect can be attributed to the above-mentioned

For example for T800T05 (where the first T denotes calcination temperature and the second T represents calcination time) the MOS cement derived from light-burned dolomite at a calcination temperature of 800C with calcination time of 05 h which was cured in 1 d the compressive strength was 135 MPa but the compressive strength of

The purpose of this work is to describe the effect of quarry dust and dolomite on the compressive strength of concrete The present examinations indicate that dolomite may be used as partial replacement of cement in concrete and quarry dust may be suitably replaced with fine aggregate in concrete to some extent The results are found to be satisfactory with the

Durability of concrete exposed to FT was assessed by periodically measuring dynamic modulus of elasticity of concrete and average depth of chloride penetration Concrete with ACBFS aggregates developed slightly higher (~6%) compressive strength but lower (~15%) flexural strength than did concrete with natural dolomite

Analysis of Scale Effect on Testing of Uniaxial Compressive Strength on Dolomite Stones at PT Polowijo Gosari Gresik East Java Erwin Rangga Fitriawan erwin Universitas Pembagunan Nasional Yogyakarta Abstract Rock mass is an arrangement composed of several intact rocks The strength of rock mass can be know from testing the intact rock

Dolomite powder has some characteristics of cement This study aims to create a concrete with low cost and is focused on the compressive strength of the concrete by partially replacing cement with dolomite powder and obtained results are examined to get optimum mix with maximum strength is determined

Correlation between Uniaxial Compressive Strength and Point Load Index for Salt-Range Rocks M Akram1 and M Z A Bakar2 1 Mining Engineering Department University of Engineering Technology Lahore Pakistan 2 Geological Engineering Department University of Engineering Technology Lahore Pakistan Abstract Nine rock types including Sandstone Limestone Siltstone 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 Two hundred rock cores were drilled and used for the uniaxial compressive strength
