건설할 창고가 필요한 건설 현장을 생각해 보십시오.
이 부지에는 창고 건설에 사용되는 너비와 깊이가 8인치, 길이가 16인치인 콘크리트 석조 블록이 쌓여 있습니다.
현장 엔지니어는 블록을 절단할 필요 없이 16인치 길이의 블록이 벽에 정확하게 배치되도록 창고를 설계해야 합니다.
계획에서 방의 치수는 바깥쪽 모서리에서 측정한 길이 12피트, 너비 8피트입니다.
블록의 실제 치수는 공칭 치수보다 약간 작습니다. 블록 치수와 모르타르 두께를 합치면 길이는 16인치입니다.
이제 벽의 긴 치수에는 정확히 9 개의 블록이 필요하고 더 짧은 치수에는 6 개의 블록이 필요합니다.
이 배열을 통해 방의 내부 치수는 긴 방향으로 10피트 8인치, 짧은 방향으로 6피트 8인치가 됩니다.
이 방법은 블록 절단을 피하고 더 빠른 시공과 완벽한 마감을 보장합니다.

설계 사례: 콘크리트 석조 구조의 치수

콘크리트 벽돌 유닛을 사용하여 창고를 건설하려면 구조물의 치수를 블록의 실제 크기와 의도된 모르타르 조인트에 맞추는 것이 필수적입니다. 문제의 부지에는 공칭 크기가 20.32 x 20.32 x 40.64cm인 콘크리트 벽돌 블록이 비축되어 있으며, 창고 건설에 사용됩니다.


 현장 엔지니어는 길이 3.66m, 너비 2.44m의 외부 치수를 가진 창고에 대한 계획을 세웠습니다. 이러한 치수에 맞추기 위해 계획은 벽의 길이에 9개의 블록을 사용하고 너비에 6개의 블록을 사용하도록 명시합니다. 그러나 각 블록의 실제 크기는 높이 19.37cm, 너비 39.37cm이며 모르타르 조인트에 0.95cm의 여유가 있습니다. 모르타르와 결합하면 40.64cm의 효과적인 블록 길이가 제공됩니다.


 이 계산은 끝에서 끝까지 놓았을 때 블록이 절단할 필요 없이 계획된 치수를 채우도록 보장하여 더 빠른 건설 프로세스를 용이하게 하고 전문적인 마무리를 달성합니다. 따라서 건설이 완료되면 창고 벽의 내부 치수는 길이를 따라 3.05m x 0.20m, 너비를 따라 1.83m x 0.20m가 됩니다. 재료 사용에 대한 이러한 체계적인 접근 방식은 건설의 효율성과 창고의 깨끗한 미적 결과를 보장합니다.

Design Example: Dimensioning of Concrete Masonry Construction

sizing a storeroom with masonry blocks

Sizing a storeroom with concrete masonry blocks starts with matching the wall plan to the actual block size and mortar joints. The site has concrete masonry units with a nominal size of 8 by 8 by 16 inches. The storeroom is planned with external dimensions of 12 feet long and 8 feet wide.

The wall layout uses nine blocks along the length and six blocks along the width. Each block is actually 7 and 5/8 inches high and wide, and 15 and 5/8 inches long. A 3/8 inch mortar joint is included, so the effective block length becomes 16 inches when the blocks are set together.

This sizing method lets the blocks fit the planned dimensions without cutting. That makes construction faster and gives the storeroom a clean, professional finish. After the walls are built, the internal dimensions measure 10 feet 8 inches in length and 6 feet 8 inches in width.

Concrete Pavement Joint Types and Functions

Concrete pavement joints guide where slabs crack and help protect the pavement over time. They support the structural integrity and long life of the concrete by controlling movement and cracking. Contraction joints, also called control joints, are made by sawing a groove into the concrete soon after it hardens. This groove creates a weakened vertical plane. It encourages cracking at a planned location instead of letting cracks form randomly across the slab. Isolation joints are used where the...

design example: aggregate gradation

Choosing Well-Graded Sand for Concrete

Well-graded sand is important in concrete because aggregate choice affects strength, mix proportions, and cost. In concrete, sand is the common fine aggregate. When more than one sand source is available, its gradation often guides the selection. Gradation means the particle-size distribution of the sand. Engineers measure it with sieve analysis, which uses standard sieve sizes from 150 μm to 10 mm, from ASTM No. 100 to the 3/8 in. sieve. This test shows how much sand stays on each sieve and...

design example: managing concrete workability

design-example-managing-concrete-workability

Concrete Slump Test in Hot Weather

Concrete slump testing helps track workability during a raft foundation pour in hot weather. Workability means fresh concrete is easy to place, compact, and finish. In this example, the concrete had to be prepared for a large foundation, so keeping it workable was important for quality and durability. The first slump test showed low workability. The mix was losing water quickly, and the high temperature made the coarse aggregates hotter as well. To reduce that effect, the site engineer cooled...

Sizing Steel Bars for a Concrete Beam

Sizing steel bars for a concrete beam helps meet a required reinforcement area. In reinforced concrete design, the steel must be arranged so the beam stays strong and uses material efficiently. This example uses a beam that needs a total steel cross-section of 4 square inches. The available bars in the example have a nominal diameter of 1.693 inches. Each bar provides a cross-sectional area of 2.25 square inches. When the engineer divides the required area by the area of one bar, the result is...

Green Features in a Concrete Building

A sustainable concrete building can use several green design features to save energy, water, and materials. Concrete is a flexible material for these choices, so it supports eco-friendly construction in commercial buildings. One strategy is to place a concrete parking area under the building. Open areas can use pervious concrete paver blocks, which let rainwater pass through and collect in an underground cistern. That stored water can then be reused for gardening, which improves water...
