Engineered Cementitious Composite (ECC), also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete, is an easily molded mortar-based composite reinforced with specially selected short random fibers, usually polymer fibers. [1]
The enlarged group has activities in over 50 countries with 51,000 employees working at almost 3,000 production sites. Heidelberg Materials operates around 130 cement plants with an annual cement capacity of around 170 million tonnes, around 1,300 ready-mixed concrete production sites, and just under 600 aggregates quarries.

However, most HPFRCCs include at least the following ingredients: fine aggregates, a superplasticizer, polymeric or metallic fibers, cement, and water. Thus the principal difference between HPFRCC and typical concrete composition lies in HPFRCCs' lack of coarse aggregates. Typically, a fine aggregate such as silica sand is used in HPFRCCs.

3D concrete printing with binder jetting technologies has been demonstrated at large scale by Enrico Dini with D-Shape. [13] D-Shape relies on a non-hydraulic Sorel cement that is based on sand activated with magnesium oxide in the powder bed and a liquid magnesium chloride solution as binder. The technology has mainly been used to create ...
Nanocem was founded as an independent consortium in 2004 after a rejection of a 2002 bid to the Network of Excellence (European Framework Programme).. Nanocem's eleven completed core projects have included studies of interactions between admixtures and cement, [4] [5] concrete durability, the kinetics of cement hydration, [6] and the use of magnetic resonance imaging techniques in concrete ...
The Advanced composites industry, or Advanced composite materials industry, is characterized by the use of expensive, high-performance resin systems and high-strength, high-stiffness fiber reinforcement. The aerospace industry, including military and commercial aircraft of all types, is the
