Ceramsite concrete body + XPS insulation core — higher strength variant
| Standard | GB/T 29060-2012 Composite Insulation Bricks & Blocks; paired with GB/T 36534-2018 ceramsite blocks |
|---|---|
| Structure | Ceramsite concrete outer body + flame-retardant XPS insulation core — modular sandwich |
| Compressive strength | MU5.0 — ceramsite body delivers higher impact & abrasion resistance than plain foam concrete |
| Bond strength | ≥156 kPa |
| Bulk density | 700 kg/m³ |
| Heat transfer coefficient K | 0.35 W/(m²·K) |
| Fire rating | A1 non-combustible |
| Standard block size | 600×240×240 mm (L×W×H); other sizes by agreement (width 100–300, height 200–300) |
| Dimensional tolerance | L: ±3 mm; W: ±2 mm; H: ±2 mm |
| Durability | Ceramsite outer layer — better surface hardiness, nail-holding, wear resistance for commercial & high-traffic walls |
| Service life | Integrated structure + insulation — same service life as the building |
| Application | Commercial walls, prefab buildings, facades, hospitals & schools; where a tougher outer shell is required |
| Parameter | Value |
|---|---|
| Compressive strength | MU5.0 |
| Bond (connection) strength | ≥156 kPa |
| Bulk (apparent) density | 700 kg/m³ |
| Heat transfer coefficient K | 0.35 W/(m²·K) |
| Fire rating | A1 (non-combustible) |
| Outer body | Ceramsite (expanded clay) aggregate concrete |
Same structural wall with insulation built in — compare against ALC panels, clay bricks and AAC blocks.
| Property | ALC Panel | Clay / Shale Brick | AAC Block | Composite Self-insulating Block |
|---|---|---|---|---|
| Compressive strength (MPa) | 5 | 10 | 5 | 5 |
| Water resistance (wet season) | Damp returns | Damp returns | Damp returns | Excellent — no damp return |
| Thermal insulation | Average | Poor | Average | Meets national 75%+ energy-saving standard |
| Waterproofing | Pores partly connected, fair | Connected pores, not waterproof | Pores partly connected, fair | Independent cement-layer pores; waterproof, insulation layer even more waterproof |
| Weight | Light | Heavy | Light | Light |
| Fixing nails / bolts | Poor nail & bolt hold | Nails & bolts usable | Poor nail & bolt hold | Nails & expansion bolts usable |
| Long-term maintenance | Insulation life ≤20 yrs, high maintenance cost | Same as left | Same as left | Same life as the building; short schedule, eco-friendly, comfortable, durable finish |
| Rendering / plastering | Needs bonding agent, high water absorption, delaminates | Good | Needs bonding agent, high water absorption, delaminates | Cement-based, same material as mortar; no bonding agent needed, strong bond |
| Construction time | Waterproof + insulation layer, long schedule | Same as left | Same as left | No separate waterproof/insulation work, short schedule |
