Phase diagram of calcium aluminates present in the anhydrous calcium aluminate cement before hydration. Calcium aluminate cements[1] are cements consisting predominantly of hydraulic calcium aluminates. Alternative names are "aluminous cement", "high-alumina cement", and "Ciment fondu" in French.

NAD-11 is an asbestos-free cement board with excellent properties. A high density cement board reinforced with inorganic fibers, NAD-11 is suitable for applications requiring continuous operation in temperatures up to 500°C (932°F).

When added to regular specialty binders, the Ciment Fondu product range makes it possible to accelerate the hardening of concretes and mortars from 3 to 30 minutes, for a quicker return to operations on small projects (after 6 hours). It can be considered fully dry after only 48 hours.

NAAD sodium (Deamido nad sodium), a functional NAD+ precursor, is the substrate of glutamine-dependent NAD+ synthetase. NAAD sodium is used to study the structure of nicotinate mononucleotide adenylyltransferases.

Here you will find certificates, declarations of performance (DOP) and the Safety Data Sheet (SDS) related to our cement types. Certain cement types are used to manufacture concrete subjected to severe exposure or special environmental conditions.

Nicotinic acid adenine dinucleotide (deamido-NAD, NAAD) is a closely related analog of NAD +. It is used to study the structure of nicotinate mononucleotide adenylyltransferase(s) (NMN/NaMN). NAAD is used as a substrate to study the specificity and kinetics of nicotinamide adenine dinucleotide synthetase(s) (NADS).

Jul 24, 2019 · Utilization of cement set time retarders, referred to as retarding admixtures, in concrete allows concrete producers to delay the set time of concrete. Retarding admixtures are commonly used in hot weather concreting and when ready mixed concrete should be transported for a long distance.

6 days ago · Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO 2), dicalcium silicate (2CaO · SiO 2), tricalcium aluminate (3CaO · Al 2 O 3), and a tetra-calcium aluminoferrite (4CaO · Al 2 O 3 Fe 2 O 3).

In randurile de mai jos iti prezentam detalii importante despre 3 produse, doua dintre cele mai importante materiale de constructii. Vei descoperi doua tipuri de ciment si un liant despre care vei afla caracteristicile si recomandari pretioase pentru pregatirea si utilizarea acestora.
