Portland cement is a key component of almost all modern concrete, accounting for more than 95% of the cement market. Concrete is typically made up of 41% crushed rock, 26% sand, 16% water, 11% portland cement, and 6% entrained air. But, despite being made from natural materials, this material carries a heavy footprint. The eco issues with concrete

Cement will remain the key material to satisfy global housing and modern infrastructure needs. As a consequence, the cement industry worldwide is facing growing challenges in conserving material and energy resources, as well as reducing its CO 2 emissions. According to the International Energy Agency, the main levers for cement producers are the increase in energy efficiency and the use of

The cement sector is the third-largest industrial energy consumer and the second-largest industrial CO2 emitter globally. Rising global population and urbanisation patterns, coupled with infrastructure development needs, drive up the demand for cement and concrete and increase pressure to accelerate action in reducing the carbon footprint of cement production.

This series of concrete calculators has been developed to help you plan your project. You can calculate how much concrete, cement, sand, mortar or render you will need. For each calculation you will have to know the dimensions of your object. The calculator will perform the sums for you - where relevant it will add a small percentage for the wastage that inevitably happens when mixing & using

Concrete is a mixture of cement with gravel, sand and possible further mineral components, such as broken stone and recycled concrete. Risks & Opportunities Risks & Opportunities • Cement production requires large amounts of energy. A reliable supply is essential for continuous output Common sources of energy are oil, coal, wood and waste. Owing to the high process temperatures, cement kilns

Cement and concrete products are well accepted as man-made construction materials. Owing to their numerous advantages (e.g., easy handling of compression forces, brittle nature that enables a rigid structure to be obtained, transportability, and durability/ability to withstand severe environments), these materials are used widely in civilian buildings and universally in infrastructures.

Cement manufacture accounts for roughly seven percent of total man-made CO2 emissions. Today, cement and concrete producers are demanding more sustainable ways to produce these materials. The good news is that approximately one third of targeted CO2 reduction can be realized through clinker replacement. And that is just one approach. In
