Fig. 2: Grinding Method to Remove Concrete Laitance 5. Acid Etching Method This method is employed for very thin concrete laitance and non-porous or low porous surface. The acid attacks and breaks down the top surface and it is a very effective method. This should only be used if other options have been ruled out. 6. Abrading Method

Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.

The benefits of using limestone as a partial replacement of Portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO 2 emissions are well known. This paper describes the influence of the producing method (intergrinding or separate grinding) and particle size distribution on properties of Portland …
