This poses a significant challenge to the cement industry directly and to the sector using it namely construction indirectly The main approaches to reduce CO 2 emissions in the production of Portland cement are Barcelo et al 2014; Carriço et al 2020 i increasing energy efficiency in the production process; ii use of alternative fuels and/or biomass; iii
Roll jaw crushers are also used for crushing raw coal and gypsum When crushing raw materials this type is normally only suited for multi stage crushing due to the low reduction factor The crusher size is given by the diameter and the width of the roller 1200 x 1600
After completion of the CTPS process the existing pipe is removed the new pipe is installed through the subsequent tight fitting void and the slurry containing the existing pipe fragments soil and bentonite fluid is removed from the ground When the patented CTPS process is used to remove and replace Asbestos Cement pipe systems
Concrete Cube Test Procedure After the specified curing time remove the specimen from the water and remove any excess water from the surface The crushing Strength of concrete is determined by taking the average of three specimens Compressive Strength Calculations The cube s size is 15cmx15cmx15cm The specimen s area calculated
Industrial attachment module is a programme that was introduced by the faculty of Engineering FoE of the University of Malawi the Polytechnic
Stage of Cement Manufacture There are six main stages of the cement manufacturing process Stage 1 Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone calcium sand and clay silicon aluminum iron shale fly ash mill scale and bauxite The ore rocks are quarried and crushed into smaller
Sintering Sintering is the process of compacting and forming a solid mass of material by heat or pressure to the point of liquefaction without actually melting it When the temperature inside the kiln reaches about 1300°C the eutectic melting point of aluminate ferrite and silicate clinker flux is produced

Cement manufacturing is a significant industrial activity that plays a vital role in the construction sector However the process of cement production is associated with various environmental
Burning In this operation the slurry is directly fed into a long inclined steel cylinder called a Rotary this kiln there are 3 different zones shown in fig below Cement Manufacturing Process Flow Chart i Drying Zones In the wet process the drying zone is comparatively larger than the dry process It is because the raw material in slurry form is directly fed into the kiln
For general construction work concrete compressive strength varies from 15 Mpa 2200Psi to 30 Mpa 4400psi and even higher in commercial and industrial structures The production of concrete compressive strength of concrete depends on different factors such as cement strength quality of concrete material water cement ratio etc
