- METHOD FOR TREATING CLAY AND CLAY-BEARING AGGREGATES AND COMPOSITIONS THEREFOR
본 발명은 고분자량을 갖고 또 폴리옥시알킬렌 기에 대한 카복실산 비율이 낮은 카복실레이트 그라프트 중합체의 사용을 포함하는, 조성물 및 방법을 제공한다. 이러한 점토감소는 점토 및 점토-보유 골재, 특히 건설 목적에 사용되는 골재를 처리하는데 특히 유용하다. 본 발명은 골재를 세척할 필요성을 최소화하므로, 건축재료에서 잔골재("미세물") 함량을 보존하여, 점토-보유 골재를 함유하는 건축재료의 성능 및/또는 특성에 유리하다.
The present invention provides compositions and methods involving the use of a carboxylate graft polymer having high molecular weight and low ratio of acid-to-polyoxyalkylene groups. Such clay-mitigation is particularly useful for treating clay and clay-bearing aggregates, particularly those aggregates used for construction purposes. The present invention minimizes the need to wash the aggregates, thus preserving fine aggregates (“fines”) content in construction materials, and thereby beneficiating the performance and/or properties of construction materials containing the clay-bearing aggregates.
