Common Types of Concrete Blocks Used in Construction
Concrete blocks form essential building materials in Chicago construction, chosen for structural strength, efficiency, and design flexibility. Each block type serves specific construction needs, supporting Lontto’s equipment offerings at every stage.
Solid Concrete Blocks
Solid concrete blocks contain dense concrete without internal voids, providing maximum compressive strength and durability. Contractors in Chicago use these blocks for load-bearing walls, foundations, and basement structures where high stability is critical. Sizes typically range from 4 to 8 inches in width, optimizing building stability. Lontto’s hydraulic block machines produce solid blocks designed for high-strength applications across large-scale projects.
Hollow Concrete Blocks
Hollow concrete blocks feature open cavities, reducing unit weight and improving ease of installation. Builders prefer them for external and internal walls in residential, commercial, and industrial structures, increasing insulation and lowering material costs. Typical cavity percentages range from 25% to 50% of the block volume, enhancing both thermal and sound insulation. Lontto’s mobile block machines, used widely in Chicago, efficiently manufacture hollow blocks for quick construction cycles.
Aerated Autoclaved Concrete Blocks
Aerated autoclaved concrete (AAC) blocks deliver lightweight construction, outstanding thermal insulation, and sound absorption. These blocks use a fine aggregate and curing process in autoclave chambers that create a uniform, aerated structure. AAC blocks weigh up to 3 times less than solid units, easing transportation and labor requirements. Mid-rise and high-rise buildings in Chicago integrate AAC blocks for energy-efficient wall systems. Lontto’s AAC block plants handle automated production for accurate dimensions and consistent block quality.
Paving Blocks
Paving blocks use dense, durable concrete that withstands heavy traffic and repeated freeze-thaw cycles. Cities like Chicago rely on these blocks to create pavements, driveways, and walkways. Available in interlocking shapes or standard geometries, paving blocks offer high wear resistance. Lontto’s paver block machines help supply municipal projects and private developments with quality paving solutions.
Lintel Blocks
Lintel blocks are designed with channels or notches to accommodate reinforcing bars over window and door openings. These blocks help distribute loads and maintain the integrity of masonry above structural gaps. Construction firms in Chicago use lintel blocks with precast or cast-in-place reinforcement for efficient installations. Lontto’s equipment can be configured to produce lintel forms matching diverse opening sizes.
Corner and Pillar Blocks
Corner and pillar blocks provide reinforced support at critical building intersections and as vertical columns. Their specialized shapes improve the strength and alignment of corners, boundary walls, and structural pillars. In Chicago’s dense urban landscape, these blocks ensure stable and visually appealing constructions. Lontto’s block machines create molds for corner and pillar profiles as part of comprehensive masonry systems.
Factors to Consider When Choosing Concrete Blocks
Selecting concrete blocks for construction depends on structural load, insulation, finish, cost, and block availability. Block strength, weight, and thermal performance all affect building durability and energy use in Chicago.
- Load-Bearing Capacity
Solid blocks and interlocking blocks carry heavier loads. For structures such as foundations or retaining walls, these types prevent cracking or settling. Testing by ASTM C90 shows solid blocks consistently reach compressive strength of 13.8 MPa (2,000 psi).
- Insulation and Weight
Hollow blocks, AAC blocks, and insulated concrete form blocks offer increased insulation and reduce wall weight. For example, hollow blocks lower dead loads in mid- and high-rise buildings, improving handling during installation. AAC blocks provide thermal insulation values up to R-23 per 8-inch thickness.
- Aesthetic Requirements
Architectural blocks and splitface blocks create design options for visible wall surfaces, enabling finishing with distinct patterns or textures. Decorative blocks are selected for projects that require both form and function in facade elements.
- Cost and Availability
Grey blocks (CMUs) cost less than ornamental or engineered block types. Lower unit cost and wide local supply make grey blocks suitable for large-scale and budget-sensitive builds. Specialized blocks such as planter wall or retaining wall units are produced in smaller batches and add to total expenses.
| Block Type | Strength (MPa) | Insulation Value (R) | Application Sample | Cost Level |
|---|---|---|---|---|
| Solid Block | 13.8 | 1.0 | Foundation, Load-Bearing Walls | Low |
| Hollow Block | 5.0–8.0 | 2.0–2.5 | Non-Load-Bearing Walls | Low |
