0183;& 32;200TPH granite aggregates production plant in Cameroon is a Sino German cooperation project. Production plants and chemical industry Concrete floors is also employed for preventing chlorine emissions in chlor-alkali plants.

Opportunities and limitations of concrete recycling

Unlike concrete based on natural aggregates, recycled-aggregate concrete contains two types of cement paste: the “new” paste creating concrete strength and the “old” paste whose parameters – such as its composition, water/cement ratio and degree of carbonation – are unknown. In addition, such concretes contain the “old” aggregates whose origin and properties are usually unknown

Electrochemical Group - Chlor-alkali and Hypochlorite Plants

Approximately 20% of NORAM's technical staff have extensive chlor-alkali plant design and operating experience. NORAM is, therefore, able to assemble a project team widely experienced in membrane chlor-alkali technology. NORAM has supplied the engineering and equipment for a grass-roots bleaching chemical complex in China.


CONTROL OF ALKALI-AGGREGATE REACTION Alkalis can come, not only from cement, but also from chemical and mineral admixtures and from the aggregate itself ⇒Total alkali content in concrete gives a better figure. Upper limit for total alkalis when reactive aggregates are used = 5-lb/yd. 3 (3 kg/m. 3).

Mitigation of Alkali-Silica Reaction in Volcanic Aggregate

Aggregates in the “Alkali-Reactive” category shall not be used. 2. Alkali content (eq. Na2O): no more than 3 Kg / m³ of concrete. b) SCCT – Construction Standard CS3:2013 Aggregate for Concrete Aggregate producers/suppliers must have a quality control system to ISO 9001 implemented.


a. Low-alkali cement. When past-performance records demonstrate that the concrete aggregate to be used for a project is potentially reactive with alkalies in the cement, a low-alkali cement will be used. b. High-early-strength cement. Concrete using Type III cement

Alkali Aggregate Reaction in Concrete - Types, Causes, and

Alkali aggregate reactions (AAR) occur when aggregates in concrete react with the alkali hydroxides in concrete producing a hygroscopic gel which, in the presence of moisture, absorbs water and causes expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms, namely: Alkali-silica reaction (ASR) and Alkali-carbonate reaction (ACR). The former []

Alkali–silica reaction - Wikipedia

The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.
