Sulfate resistant concrete with aluminosilicate additives
Journal Title: Architecture Civil Engineering Environment - Year 2017, Vol 0, Issue 0
Abstract
The paper observes an improvement of the sulphate resistance of concrete. This was achieved through creation of dense con- crete structure with sulphate resistant binder matrix. Series of tests confirms the positive effect after optimizing the sieve line, also in very fine area; reducing the water-cement ratio with superplasticizer on polycarboxylate basis and restriction of the sulphate sensitive clinker. These steps were possible through adding active aluminosilicate mineral additives. They improve fresh concrete properties, density and corrosion resistance of concrete. The chemical reasons of such effect were explained by the means of x-ray diffraction, differential thermogravimetry and scanning electron microscopy. This develop- ment should be widely used in several projects in Ukraine, where sulphate-resistant concrete is needed.

Cadmium and lead content in the barrier dusts sampled from the noise barriers located near to Poznań (Poland) – a preliminary study
High levels of heavy metals in the environment are dangerous for humans due to possible bioaccumulation of such contaminants by edible plants and herbivores. In this study, total content of cadmium and lead in the barri...
Silesian conurbation as a polycentric structure of urban districts
The Silesian conurbation consists of cities, which in many aspects function as one metropolitan organism. This paper is an attempt to characterise the structure of the Silesian conurbation not as composed of cities, but...
