SpECbuild SG15 Structural-grade Cementitious Repair Mortar Pre-bagged, one part cementitious repair compound. After the addition of clean water a high strength, non-shrink mortar is produced. USES SpECbuild SG15 is designed to provide a structural grade repair mortar particularly in situations where abrasion resistance and low permeability are required, such as: • Repairs to structural concrete elements, e.g. reinforced beams and columns • Highly trafficked surfaces, particularly transition strips adjacent to mechanical bridge joints • Repairs in marine environments or other situations where concrete is in contact with chloride or sulfate solutions FEATURES • High bond strength to concrete substances. • Good abrasion resistance. • High compressive strength. • Coefficient of thermal expansion similar to host concrete. • Compensated for plastic and long-term shrinkage • Low permeability providing protection against the ingress of chlorides and carbon dioxide
