Residential Concrete Construction Instructions Detail Sheet

Comprehensive reinforced concrete specifications and construction details for residential structural elements. Key Specifications: C30 concrete (30 MPa characteristic strength) with water/cement ratio <0.60, 12±2cm slump using grade 1 crushed stone aggregate. Designed for Class II environmental aggression (urban region) with precise concrete, overall, cover requirements: 2.5cm for beams/columns, 2.0cm for slabs/stairs, and 3.0cm for foundations (±0.5cm tolerance).

Construction Guidelines:

• Lateral formwork removal permitted after 3 days
• Bottom formwork removal after 10 days (maintaining 50% shoring until 28 days)
• Floor shoring cannot be completely removed until two superior slabs are concreted
• 7-day concrete curing required using water or impermeable film

Includes detailed illustrations for vibration spacers, layer spacing, beam cross-sections, column clamps, and anchor/lap length values for various rebar diameters (6.3-20.0mm). Generic detail for beam penetrations showing reinforcement approach around openings.
