The Construction Products Regulation CPR requires that from 1 July it is mandatory for many, but not all construction products to have CE markings in order to be placed on the market anywhere in Europe.
Exemptions include site-batched products, ready-mixed concrete and products without a harmonised European standard, such as reinforcement, but also bespoke products, such as bespoke precast concrete. CE stands for Communaute Europeenne. CE marking communicates that a product meets a set of basic European harmonised standards, or a European Technical Assessment. Each product with CE markings has a Declaration of Performance DoP that is made available to purchasers and specifiers.
It continues to list CE marking as just one way in which the suitability of a material can be assessed for use for a specific purpose and advises that the declared performance of a material with CE marking is checked for suitability for the building works proposed.
For many standardised products, CE marking may become the default requirement by Building Control Officers to demonstrate material suitability, but for many others, particularly bespoke solutions, other means of compliance will continue to be used. There remains no requirement for proof of CE marking to be routinely supplied for Building Control approval. No , not all products need CE marking. As explained above, CE marking is a symbol that the product has met a harmonised standard.
Some products do not have a harmonised standard and even then there are exemptions. Where there is ambiguity specifiers should seek guidance from manufacturers and their trade associations. Specifiers should understand that CE marking was not intended as a quality standard and that current EN and BS standards remain the correct references for specification.

The Portland cement concrete is the most popularly used building material around the world. However, there are major drawbacks associated with Portland cement, such as the emission of greenhouse gasses and high-energy consumption from cement production. Therefore, Portland cement concrete has many disadvantages that can only be overcome by being replaced with new materials such as fly ash-based green cement. Recycling fly ash and using it to replace cement has positive impacts on our environment, such as conserving landfill spaces, reducing CO2 emissions, and saving energy. Fly ash can be further recycled into value-added building products by using fly ash-based green cement. Two experimental works were undertaken to evaluate the durability performance of fly ash-based green cement mortar for freezing-thawing resistance and the other for compressive strength. Finally, a benefit-cost model analysis of using fly ash-based green cement in masonry units is conducted.

A cement is a binder , a substance used for construction that sets , hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel aggregate together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel , produces concrete. Cement is the most widely used material in existence and is only behind water as the planet's most-consumed resource. Cements used in construction are usually inorganic , often lime or calcium silicate based, and can be characterized as either hydraulic or non-hydraulic , depending on the ability of the cement to set in the presence of water see hydraulic and non-hydraulic lime plaster. Non-hydraulic cement does not set in wet conditions or under water.

Приоткрыв дрожащие губы, она попыталась что-то сказать, но слов не последовало. Не спуская со Стратмора ледяного взгляда, Сьюзан сделала шаг вперед и протянула к нему руку с зажатым в ней предметом.
Стратмор был почти уверен, что в руке Сьюзан сжимала беретту, нацеленную ему в живот, но пистолет лежал на полу, стиснутый в пальцах Хейла. Предмет, который она держала, был гораздо меньшего размера.
Стратмор опустил глаза и тут же все понял.
