Innolayn NC40 RF3 — R4 grout for work at −25…−10 °C
Cementitious R4 grout for installing equipment, columns, joints and anchors at sub-zero temperatures; 15 MPa after 6 hours at −25 °C.

Steel reinforcing fibre, supplied as a separate component, distinguishes Innolayn NC60 SFiber from the standard NC60: the flexural strength of this grout is at least 10 MPa after 24 hours and 14 MPa after 28 days, the compressive strength 30 and 60 MPa. Component A consists of cement, graded sand and modifying admixtures. The grout is used for high-precision installation of presses, machine tools, generators, pumps and compressors, under column bases and for repairing heavily reinforced structures, bridges, roads, airfields and car parks by pouring.
