Diverse types meet various functional needs:load-bearing,non-load-bearing,insulating,decorative.Low production energy,utilizes industrial by-products(fly ash),environmentally friendly.High laying efficiency,saves mortar.Uniform dimensions promote wall flatness.Some feature tongue-and-groove designs for easier alignment.Insulating blocks achieve thermal performance through cavity design or filled insulation.
Primary nominal size is 390mm×190mm×190mm.Strength grades range from MU3.5 to MU20.Classified as hollow or solid based on cavity percentage.Density grades range from 600 to 1400 kg/m³.Specific requirements exist for freeze-thaw resistance,drying shrinkage,etc.
For internal and external wall construction in buildings;the main infill material for framed structures.Building garden walls,planters,etc.Special blocks for specific uses:insulating blocks for energy-efficient walls,architectural blocks for facades,paving blocks for sidewalks/plazas.Requires proper tying to structural elements like columns and beams.
