High Performance Concrete Additives

Water ReducingAccelerating AdditivesAir-EntrainmentShrinkage ReducingCorrosion-InhibitingSuper PlasticizersPrecautions in Use of Concrete AdditivesThese are used to reduce the quantity of mixing water required to produce concrete of a certain slump, reduce water-cement ratio, reduce cement content, or increase slump. They are used extensively on larger projects where reinforcing steel requires high workability. Also used in precast and on site where the large water reduction provides very high early strength and improved durability. Water reducing additives usually reduc在constructionreviewonline上查看更多信息

Seven Must-Use Concrete Admixtures (Additives)

ApplicationsBenefitsAdvantagesSet retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavements, reducing additional c在thebalancesmb上查看更多信息

Strength development in concrete - Understanding

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may ...

批量生产的增材制造 维捷

The technology called Industrialization of Core Printing (ICP) allows automated production of highly complex sand cores for casting processes. By harnessing the flexibility of additive manufacturing, ICP eliminates design limitations of conventional tooling and is capable of matching conventional core making in serial-production.

Investigation of concrete by of means of micro-XRF ...

In this webinar we will discuss the analysis of concrete by elemental mapping of the surface of a drill core using the M4 TORNADO PLUS micro-XRF spectrometer. In particular, a comparison of the analytical performance between the excitation by different X-ray tube source materials will be shown, namely rhodium (Rh) and silver (Ag).
