Cement Concrete Cover Blocks
Cement concrete cover blocks are precast spacers used in reinforced concrete construction to maintain a consistent distance between steel reinforcement and the formwork. The blocks from Huaxian Qingzhong Machinery Factory are manufactured using a mix of cement, fine aggregate, coarse aggregate, and water, with standard dimensions of 25mm, 40mm, and 50mm thickness. These dimensions ensure compliance with common structural codes requiring minimum concrete cover for corrosion protection of rebar.
The blocks are produced under controlled conditions to achieve compressive strengths typical of structural concrete, generally ranging from 20 MPa to 30 MPa. They are not coated or treated, relying on dense curing for durability. In the industry, such blocks are often classified as non-structural spacers and are not load-bearing, but critical for maintaining design integrity. Packaging is typically in bundles or on wooden pallets, with quantities varying by block size and order volume.
These blocks are primarily purchased by civil contractors, precast manufacturers, and infrastructure project managers working on residential, commercial, and public works projects. Buyers commonly source them in bulk for large-scale pours where consistent cover is required across hundreds of cubic meters of concrete. Trade terms are typically FOB from Anyang port, with lead times dependent on production scheduling and seasonal labor availability, particularly during summer months when production is adjusted for heat management.
| Material composition | Cement, fine aggregate, coarse aggregate, water |
| Standard thicknesses | 25 mm, 40 mm, 50 mm |
| Typical compressive strength | 20 MPa to 30 MPa, standard for structural concrete spacers |
| Density | Typical density of 2300 kg/m³ for normal weight concrete |
| Surface finish | As-cast, no surface treatment applied |
| Packaging | Bundled or palletized, typical for bulk construction supply |
| Typical tolerance on thickness | +/- 1 mm, standard for precast concrete spacers |
| Curing method | Steam or ambient curing, typical for industrial precast operations |
| Typical weight per block (50mm) | Approximately 1.8 kg, based on standard density and dimensions |
| Compliance reference | Typically conforms to ASTM C94 and EN 12390-1 for concrete quality |

Sourcing Cement Concrete Cover Blocks from Huaxian Qingzhong Machinery Factory - China Import Guide
Before ordering, verify the compressive strength of the batch with a test report, confirm the exact dimensions of each block size, and inspect samples for surface cracks or uneven curing. These blocks are not certified products, so buyers must rely on physical inspection and supplier-provided test data. Ensure the supplier can deliver consistent batch-to-batch quality, especially during seasonal production changes.
Lead times are affected by summer heat management protocols, which may slow production. Confirm whether the supplier uses FOB Anyang port or another incoterm, and clarify if pallets are returnable or disposable. Payment terms are not stated, so request standard arrangements such as 30% advance and 70% against shipping documents. Confirm packaging compatibility with your shipping container dimensions.
Conduct a pre-shipment inspection focusing on block uniformity, absence of honeycombing, and correct thickness. Request a certificate of conformity referencing the mix design and curing duration. Document the condition of packaging upon arrival. Since no certifications are provided, buyers should arrange independent third-party testing for critical projects, particularly where structural integrity is non-negotiable.
