Treatment fluids and methods for treating a subterranean formation include introducing a treatment fluid into a subterranean formation, the treatment fluid containing a nanocrystalline cellulose. The treatment fluid may be a fracturing fluid, well control fluid, well kill fluid, well cementing fluid, acid fracturing fluid, acid diverting fluid, a stimulation fluid, a sand control fluid, a completion fluid, a wellbore consolidation fluid, a remediation treatment fluid, a spacer fluid, a drilling fluid, a frac-packing fluid, water conformance fluid or a gravel packing fluid.
摘要:
A limestone based masonry veneer composition is described that may be molded, blown, sprayed, troweled, or otherwise applied to interior and exterior surfaces. The composition provides an aesthetic resurfacing, cladding and/or overlay coating. The composition is capable of being pigmented, textured, sculpted-or otherwise formed into an aesthetic, realistic, architecture, suitable as a stone veneer, an example of which is Blown Stone®, by Stone Coat®. Texturing or sculpting may occur about 1 hour and up to about 12 hours after applying the composition. The final composition is hydrophobic and breathes. Air carbonation allows the formation of a predominantly very pure calcium carbonate or limestone when fully cured, which prevents mold and algae growth and allows for autogenous healing with an increase in unit weight over time, ensuring an overall high compressive strength that endures over time.

본 발명은 콘크리트포장이 시공되는 기층에 연속철근을 배근하고, 배처플랜트에서 압축강도 21~30MPa의 보통콘크리트를 생산하여 현장 이송 후, 체적 대비 20~40%의 기포를 혼입하여 유동성을 증가시킨 상태에서 플라이애쉬나 슬래그미분말 중 어느 하나 또는 이를 혼합한 저급 혼합재료를 혼합부로 혼합하여 형성한 보통강도 콘크리트 또는 상기 보통콘크리트에 기포를 혼입하여 유동성을 증가시킨 상태에서 실리카퓸, 메타카올린, 라텍스, 폴리머, 착색재료 중 어느 하나 또는 하나 이상을 혼합한 고급 혼합재료를 혼합부로 혼합하여 형성한 고성능 콘크리트를 숏팅하여 연속철근 콘크리트포장을 시공함으로 고강도와 고내구성을 확보하여 유지관리를 용이하게 함은 물론 숏팅되는 보통강도 콘크리트와 고성능 콘크리트의 다짐이 필요 없음으로 슬립폼 페이버의 경량화로 시공의 수월성을 제공할 수 있는 기포 숏크리트를 이용한 연속철근 콘크리트포장 시공방법에 관한 것이다.
摘要:
A deformable particulate material made of cement materials such as aluminosilicate cement and having an aspect ratio of greater than 1 to about 25 may be mixed with conventional proppants to give a blend with improved flow back capacity when the blend is injected into a hydraulic fracture created in a subterranean formation.
