The "Acid Test" for Carbonate Minerals and Carbonate Rocks

The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric

Carbonation resistance of concrete: limestone addition

12/12/2016  Although historically the use of limestone (LS) as a construction material dates back to ancient times, when calcined LS or gypsum was used to make mortar (Mayfield, 1990) and when LS became one of the main constituents of the raw feed used to manufacture Portland cement clinker in 1824, it is the acceptance of LS as an addition to cement with Portland clinker (EN 197-1, 2000 ()), to

THE EFFECT OF ADDITION OF LIMESTONE POWDER ON

The test results are given in Table 4 and plotted in Fig 9. It has been observed that the 28-day flexural strength increases up to 20% replacement of cement by limestone powder but further addition of limestone powder decreases flexural strength. From the Fig 9 it has been observed that the best-fit polynomial equation for flexural strength is

The Acid Test: What does Vinegar do to a Rock

This time, instead of testing the property of a rock, we're going to test for a specific type of rock -- limestone! This is also referred to as the Acid Test for Rocks (but we're using a much safer form of 'acid'). In addition to the detailed tutorial on how to test your rocks, we're also including affiliate links for items that will be helpful

The chemistry of limestone

The colour of a piece of limestone may be misleading. For example coarse brown limestones may be wrongly described as sandstones. (Limestone comes in almost every imaginable hue from white, through yellows, reds, oranges, blues, purples, olives to browns and black.) These colour variations are almost all due to iron content. Some of the
