Dry Polymers Vs Wet Polymers: A detailed Analysis ...

The polymer curing admixture's primary and all-important purpose is to maintain the concrete's internal moisture levels so that the GFRC's Portland cement paste continues to hydrate (cure) even when the piece sits in the open air. The polymer does this by essentially forming an internal curing membrane, slowing moisture loss.

US6213415B1 - Process for improving grinding of cement ...

An exemplary process for grinding cement clinker using rollers comprises introducing cement clinker into grinding contact with rollers operative to grind the clinker into particles; and introducing to the clinker and/or rollers, in an amount of 0.001-0.5 percent based on the dry weight of clinker, a binding-densifying agent comprising at least one polymer having an average molecular weight of ...

Preparation of polymer-based cement grinding aid and their ...

Polymer-based grinding aids increased the fluidity of ground cement. Abstract This paper described a chemical process called water-based free radical polymerization to synthesize a polymer-based grinding aid (PGA), which was characterized by infra-red spectroscopy (FT-IR) and used for the production of Portland cement (ground in a ball mill at ...

Development and use of polymer-modified cement for ...

In the post-addition method, the control cement already ground to targeted fineness was considered for testing, while latex was diluted with 10% mixing water prior to batching. The cement properties obtained following polymer inter-grinding and post-addition methods are summarized in Table 2, Table 3, respectively.

US6005057A - Cement grinding aid - Google Patents

A cement clinker grinding aid which comprises a styrene-maleic anhydride copolymer (SMA) superplasticiser. The SMA is preferably a type with polyoxyalkylene-based side chains. Use of the grinding aid renders the grinding process more efficient and improves the performance of cementitous compositions in which the cement thus ground is used.
