Sulphate resistance is frequently the subject of cement chemistry-related questions. Why do we need to resist sulphate and where? Is there a downside to sulphate-resistant clinker? Sulphate is an essential component of Portland cement but, as with all good things, it must be taken in moderation. Excessive sulphate can lead to catastrophic ...

Even though not practical mixtures such as C 100 G 0 were evaluated in this work, this was purely from a mathematical point of view in order to obtain a better sampling of the independent variables (i.e. the mixture composition) using a simplex-centroid design.. Resistance to Grinding. A total of 700 ml of each blend were introduced in a 0.30 m cast iron drum (BICO …

For portland cement types, ASTM C150 describes: Cement Type Description. Type I Normal. Type II Moderate Sulfate Resistance. Type II (MH) Moderate Heat of Hydration (and Moderate Sulfate Resistance) Type III High Early Strength. Type IV Low Heat Hydration. Type V High Sulfate Resistance. For blended hydraulic cements – specified by ASTM C595 ...
The exposure solutions were tap water containing 5% magnesium sulfate solution and 5% sodium sulfate solution. Two types of grinding method (separately grinding and intergrinding, two finenesses (250 m2/kg and 500 m2/kg) and three different proportions (10%, 20%, and 30% by weight of mixture)) of each of two different additives (GGBS and NP) in ...
Sulfate Resistance Cement SRC 52.5N. When sulfates are present in the soil and groundwater, Portland cement is damaged. Where sulfates generate a series of chemical reactions that take place in the presence of sulfur ions, thus producing a larger volume of auxiliary reactions and thus causing internal expansion and damage to the concrete ...
The blended cement specimens (C 3) exhibited greater sulfate resistance than any of the other specimens. 2. No particular relation has been observed between the sulfate resistance of mortars and the grinding process. 3. At 36 months, the strength reduction for mixes C and E in MgSO 4 is marginally lower than in Na 2 SO 4. For specimen D tested ...

Pakistan is the 14th largest manufacturer of cement in the world. There are various types of cement that are used in the construction industry for different purposes. Today, we are going to look into two distinct types of cement. One is Ordinary Portland Cement (OPC) and the other one is Sulphate Resistant Cement (SRC).
Assessing the sulfate resistance of concrete is essential for the use of concrete in sulfate rich environments. A multitude of test methods exists worldwide, showing the relevance of the problem and the difficulty to find a suitable test setup. Testing the relative tensile strength of ASTM C307 concrete briquette specimens after exposure to a sulfate solution is a new direct …
Sulfate-resistant cement is made on the basis of the crumb of a portland cement clinker of fine grinding in a mixture with plaster, a special case of an ordinary portland cement with a feature in the form of increased resistance to sulfates.

finer grinding of the slag component increases the sulphate resistance if the cement contains more than 65% slag, and lowers the sulphate resistance if the slag content is below 65%. x-ray investigation showed portland cement free from tricalcium aluminate to be sulphate-resistant because its hydration products cannot react with sulphate.
