...Behzad Elahifar; Erfan Hosseini The study uses chemical and mineral admixtures to understand the critical processes affecting the cement slurry characteristics, including rheological properties, free water, compressive strength, and thickening time. Using alternate mineral admixtures to replace...

... could be used for cementitious material, road concrete, and road base material. The masonry cements, road concrete with 30 MPa compressive strength and 4.0 MPa flexural strength, and the road base material used for base courses of the expressway, the main road and the minor lane were all prepared...

... at the end of the first groove were 7000 psi (48 MPa) for perfect contact analysis and 18,000 psi (124 MPa) for imperfect contact analysis for an applied pressure of 35,000 psi (240 MPa). The maximum diametrical compressive strength for the epoxy is 10,000 psi (68.9 MPa). The hoop or the circumferential...

... with different tooth wear (T0, T4, T7). Drilling media used for the tests were soft to medium-hard rocks whose uniaxial compressive strength ranged from 14 to 118 MPa. Based on the test results, a parameter, which presents the rock strength independent of the tooth wear, was first investigated. The investigation...
