Review, confirm and verify all relevant information and data that can be verified by the client, and study and evaluate the risks assigned to him. Because under the ERS contract, all controllable information, except for specific numbers and information provided by the customer, is considered to have been reviewed and checked by the contractor, and the related risks are assigned to the contractor. It should be noted that due to insufficient time until the submission of the tender, it may not be possible to check and confirm the above information and calculate the risk. Also, the cost of the contractor's research at the tender stage and preliminary design proposal to meet the customer's requirements is relatively high.
It is recommended that the contractor calculate the contract price during the design development, procurement, access to the work site, execution of work, testing, handover of work, and the risks arising during the Qatar Mobile Number List period of notification of defects, and include the additional costs that may arise in this regard to a certain extent. Cement production alone accounts for 8-10% of global greenhouse gas emissions. Cement plants are actively looking for ways to reduce their CO 2 emissions and energy consumption. Experiments on the technology of producing calcium silicate binding materials using natural raw materials containing SiO 2 and CaO are intensively conducted in other countries. One of them is Celitement, which has the advantage of using 50% less energy and reducing greenhouse gas emissions by 50% compared to Portland cement.
The technology for extracting hydraulic retaining material to replace cement from raw materials and waste containing a lot of quartz sand, silicon and aluminum oxide was first developed at the Karlsruhe Institute of Technology in Germany and the product was named Celitement.
The technology is based on the process of extracting calcium hydrate silicate by mixing quartz-containing raw materials and waste with burnt lime and processing it with steam in an autoclave at a temperature of 160-200°C.
