Improving concrete and mortar using modified ash and slag cements
Presents the results of a study of high-tech concrete on composite Portland cement and slag Portland cement. The possibilities of significantly improving the properties of cements and concrete with the introduction of superplasticizers and hardening activators are shown. Experimental dependences that make it possible to predict the properties of concrete and mortars and to design mixtures with given properties are given.
Fiber Concrete : In Construction
Helps the user to correctly use fiber-reinforced concrete as a building material in accordance with its properties in order to create a long-lasting building for the client at low cost. Fiber-reinforced concrete as an extension of concrete offers considerable advantages for building practice, which, based on the material properties, enable a very long service life.Fiber-reinforced concrete is particularly suitable for an aggressive environment such as salt exposure, since corrosion can be completely avoided. Particular attention is also paid to the shrinkage cracks that occur in the concrete and how they can be and how these can be avoided when using fibers.
