Considere un sitio de construcción que necesita un almacén para ser construido.
El sitio tiene una pila de bloques de mampostería de concreto con dimensiones nominales de 8 pulgadas de ancho y profundidad y 16 pulgadas de largo utilizados para la construcción del almacén.
El ingeniero de obra tiene que diseñar el almacén para que los bloques de 16 pulgadas de longitud se coloquen con precisión en las paredes sin tener que cortar los bloques.
Las dimensiones de la habitación en el plano son 12 pies de largo y 8 pies de ancho, medidos desde las esquinas exteriores.
Las dimensiones reales del bloque son ligeramente inferiores a las dimensiones nominales. Las dimensiones del bloque y el espesor del mortero juntos dan una longitud de 16 pulgadas.
Ahora, se necesitan exactamente 9 bloques para la dimensión más larga de la pared y 6 para la más corta.
Con este arreglo, las dimensiones internas de la habitación se convierten en 10 pies y 8 pulgadas en la dirección más larga y 6 pies y 8 pulgadas en la dirección más corta.
Esta práctica evita el corte de los bloques y asegura una construcción más rápida y un acabado perfecto.

ejemplo de diseño: dimensionamiento de una construcción de mampostería de hormigón

Para la construcción de un almacén con bloques de mampostería de hormigón, es fundamental adecuar las dimensiones de la estructura a las dimensiones reales de los bloques y a las juntas de mortero previstas. En el solar en cuestión se encuentra apilado un conjunto de bloques de mampostería de hormigón de tamaño nominal 20,32 x 20,32 x 40,64 centímetros, que se utilizarán en la construcción del almacén.

El ingeniero de obra ha diseñado un plano para el almacén con unas dimensiones externas de 3,66 metros de largo y 2,44 metros de ancho. Para adecuarse a estas dimensiones, el plano especifica el uso de nueve bloques para el largo de las paredes y seis bloques para el ancho. Sin embargo, el tamaño real de cada bloque es de 19,37 centímetros de alto y 39,37 centímetros de ancho, con un margen de 0,95 centímetros para la junta de mortero. Cuando se combina con el mortero, esto proporcionará una longitud de bloque efectiva de 40,64 centímetros.

Este cálculo garantiza que, una vez colocados los bloques uno tras otro, ocuparán las dimensiones previstas sin necesidad de realizar cortes, lo que facilita un proceso de construcción más rápido y consigue un acabado profesional. De esta forma, las dimensiones interiores de los muros del almacén serán de 3,05 metros 0,20 metros de largo y 1,83 metros 0,20 metros de ancho una vez finalizada la obra. Este enfoque metódico en el uso de los materiales garantiza la eficiencia en la construcción y un resultado estético limpio para el almacén.

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...
