Class H-HSR Ce m e nt
The Holcim Apasco´s Class H-HSR Pórtland Cement is a very High Sulfate Re s i s t a n ce pro d u ct, Low Alka l i - Aggregate Re a ctivity and ve ry LowHydratation Heat specially designed to be used in Geotermic & Petroleum production works.

Applications The high variations present in the Oil Cements due the a d m i x t ure s, observed between batches pro d u ced of Class API Cements, as well as the severe conditions of some oil wells in México, are factors that force to make grout designs, sophisticated, difficult tocontrol, expensive due to the high percentage of admixtures taking part requiring too much time in the design, affecting the waiting time in the oil wells. This lead us to the Class HHSR Cement thatthanks to its physic-chemical properties, this product is the recommended to cement oil wells where the temperature conditions raise up to 165°C and pressure of 36,000 psi at 9,000 m depth. Also, it isthe ideal cement to make grouts used to cement oil & geotermic wells, wich are exposed to the action of aggressive agents – like sulfates, chlorides, aggressive formations and high temperature &pressure conditions. Characteristics The Class H-HSR Cement gives to grouts: high compressive strength, excellent resistance to chemical attack, optimums hydraulic seal between soil stratums and lowadmixture consumption, turning into a product with suitable technical characteristics and economically profitable. The Holcim Apasco´s Class H-HSR Cement meets widely the quality standards set up by theAmerican Petroleum Institute (API-Esp-10) and the standard NRF-069-PEMEX. The cement plant pro d u cer of the Class H-HSR Ce m e nt comply with the API Certification as well as the ISO 9000. Benefits -High Sulfate Resistance to guarantee the oil wells durability. - Low Alkali-aggregate Reactivity. - Suitable characteristics to support high temperatures & pressures. - Good reologic performance in...
