Jaw crushing plant is primarily used for reducing various kinds of stones and lump materials into medium-grained gravel. The materials to be crushed can be hard‚ medium-hard and soft minerals which compressive strength should be not more than 320 MPA. Our PE series jaw crusher result in higher crushing efficiency. Currently‚ these products become the preferred jaw crusher machine in the production of stone. They are widely used in many industries‚ such as mining‚ metallurgy‚ building material‚ railway

Effect of mixing time on fly ash block property Ayan Kumar Keora a a Development Alternatives‚ B-32‚ TARA Crescent‚ Qutab Institutional Area‚ New Delhi – 110016‚ India Abstract: This paper presents the effects of mixing time on the compressive strength of fly ash brick. Before designing the mix‚ sieve analysis of sand and fly ash was carried out and their fineness moduli were determined. Also the specific gravity and calorific value and ash content of fly ash were determined. The CaO content

rock surface being tested. Rebound hammer test is frequently used in estimating the compressive strength of joint surface in rock. The value of R can be used to estimate the compressive strength of rock using the following equation (Franklin‚ 1989): Log10 JCS = 0.00088(γ)(R) + 1.01 Where‚ JCS (MPa) is the compressive strength of rock surface; γ is unit weight of rock (kN/m3). The term JCS means joint compressive strength‚ which implies the surface strength of joints (fracture planes) in rock. This

Care and Support for Veterans with PTSD Post-traumatic stress disorder is among the leading diseases that veterans face after their time in the military. Most veterans‚ some being homeless‚ have some form or symptoms of PTSD. This disease destroys veterans’ lives one day at a time. Veterans with PTSD go unsupported and uncared for every single day. Veterans who suffer from PTSD need more support from the government they served under and from the people they protect. PTSD affects not only the mind

properties including the unit weight and the compressive strength has been reported based on the variation in its ingredient proportions. The unit weight of EPS composite soil‚ which ranges from 5 to 18 kN/m3‚ is lighter than that of natural soils because of adding super-light EPS into the mixture. The reported values of compressive strength are in the range of 50~550kPa‚ which meet almost all the requirements for fill materials. Both the unit weight and the compressive strength of this geomaterial can be

METHODS OF RAFT FOOTING DESIGN According to IS – 2950:1965‚ the design criteria of raft footings are given below: The maximum differential settlement in foundation on clayey soils and sandy soils should not exceed 40mm and 25 mm respectively. The maximum settlement should generally be limited to the following values: Raft foundation on clay – 65 to 100 mm. Raft foundation on sand – 40 to 65 mm. There are two methods for the design of raft foundations. They are: 1) Conventional Method 2)

Post Traumatic Stress Disorder (PTSD) has been the focus of considerable attention‚ and some controversy‚ since it was formally recognised in 1980 by the American Psychiatric Association. This essay will discuss the history of this relatively new diagnosis and its place within the DSM-IV-TR‚ whilst three perspectives of pathological reaction to trauma‚ namely‚ socio-cultural‚ psychological and biological factors will also be compared. In conclusion this essay will discuss how the three perspectives
