Short answer: AAC (autoclaved aerated concrete) block costs roughly ₱131 to ₱523 per piece as of August 2026, depending on thickness (100mm–250mm) and strength grade. A standard 100mm partition block in a mid-range grade runs about ₱169/piece; a 200mm structural-grade block runs ₱382–₱419/piece. Unlike CHB, AAC suppliers quote per square meter as the default unit — the table below converts every thickness and grade to a per-piece price too, since that's what most buyers actually search for.
100mm, per piece: ₱169 · 100mm, per sqm: ₱1,405 · 200mm, per piece: ₱326 · 200mm, per sqm: ₱2,719
AAC suppliers grade blocks by compressive strength (measured in psi). Higher psi means denser material and higher cost, but more structural capacity per piece. Prices below are per square meter (the supplier's standard unit) with the per-piece equivalent calculated at 8.33 pieces/sqm — the standard count for a 600mm × 200mm block face.
| Thickness | Ecolite (~508psi) | Eco (508–580psi) | Optimum (600–725psi) | Optimum+ (800–870psi) |

Enter your wall area and pick a thickness and grade for an indicative material cost.
AAC's strength grade determines what it's structurally appropriate for — using a light partition grade on a load-bearing wall is a real defect, not just a cost-saving choice gone too far.
Ecolite (~508psi) — Light Partitions
The lightest and cheapest grade. Suited for non-load-bearing interior partitions only — not exterior walls, not anything carrying roof or floor load.
Eco (508–580psi) — Standard Walls
The most commonly specified grade for typical residential walls — interior partitions and light exterior walls in a standard house build. This is the grade most price comparisons (including this one's quick reference) default to.
Optimum (600–725psi) — Load-Bearing
Higher compressive strength for exterior walls, perimeter walls, and applications where the wall itself carries meaningful load — always confirm the specific load path with your structural engineer before specifying AAC as load-bearing.
Optimum+ (800–870psi) — Structural / Heavy-Duty
The densest, most expensive grade — for structural applications and projects in typhoon-exposed areas where higher impact resistance and load capacity are specified.
AAC blocks are internationally specified under ASTM C1693 (Standard Specification for Autoclaved Aerated Concrete), the standard most Philippine suppliers reference for density and compressive strength grading — always confirm your supplier's test certificates match the grade quoted.
CHB only comes in 100mm and 150mm — AAC's larger 200mm and 250mm options don't have a CHB equivalent to compare against. At the two thicknesses they do share, AAC block material costs roughly 6 to 17 times more per piece than CHB, depending on grade and buying channel: 150mm CHB runs ₱19–30/piece (see AEDO's CHB price guide) versus ₱189–314/piece for 150mm AAC across grades (this table). That's a much wider gap than it looks once installed, though — AAC's larger, precision-cut pieces need less mortar and go up faster, so the total installed cost gap narrows to roughly 2 to 3 times per sqm, not 6 to 17 times. For the full performance comparison (strength, insulation, typhoon resistance, total installed cost per sqm), see AEDO's CHB vs AAC blocks comparison.
These per-piece prices are derived directly from a Philippine AAC supplier's published August 2026 price list (per sqm, converted here to per-piece at 8.33 pcs/sqm), and refine the broader ₱350–₱550/piece estimate quoted in AEDO's CHB vs AAC comparison — that earlier figure was a general market range across grades; the table above breaks it out by exact thickness and grade. Actual price varies by region, freight distance, and order volume. Always confirm current pricing with your supplier before finalizing a budget.
How much does an AAC block cost per piece in the Philippines?
Roughly ₱131 to ₱523 per piece as of August 2026, depending on thickness (100mm–250mm) and strength grade. A standard 100mm block runs about ₱169/piece; a 200mm structural-grade block runs ₱382–₱419/piece.
Why do AAC prices vary so much by grade?
Higher-psi grades use a denser mix for greater structural capacity — a 200mm block ranges from ₱252/piece (Ecolite) to ₱419/piece (Optimum+), same size, different load rating.
How many AAC blocks per square meter?
8.33 pieces per sqm for the standard 600×200mm face, before waste allowance (typically 3–6%).
Is AAC more expensive than CHB?
Yes — roughly 6 to 17 times more per piece at the thicknesses both share (100mm/150mm), though that gap narrows to roughly 2 to 3 times for total installed cost per sqm, since AAC's larger pieces need less mortar and labor.
AEDO's design-build service includes material sourcing and quality control for AAC, CHB, and every other component — under one contract, for projects located in Negros Oriental. For projects elsewhere in the Philippines, AEDO provides complete structural design with remote engineering oversight, and can refer you to a vetted local contractor for the actual construction.
