a. Cube/Cylinder Crushing Test

The cube or cylinder crushing test is a common laboratory test conducted on concrete samples to assess their compressive strength. It is an important parameter used to determine the overall quality and performance of concrete in structural applications. The cube or cylinder crushing test provides an indication of the concrete’s ability to resist compression. Either cube or cylindrical mould is used for preparation of test samples. After casting the specimen on the mould, the sample is cured sufficiently for 28 days which allows the strength development of concrete. Then, the specimen is loaded with gradually increasing compressive load until the failure occurs. This gives us the required compressive strength value of the specimen.

b. Interlocking Block

Interlocking blocks, also known as interlocking concrete blocks or interlocking pavers, are modular units made of concrete or other materials. They are specifically designed to fit together like puzzle pieces, creating a stable and durable structure without the need for mortar or adhesive. Interlocking blocks come in various shapes, sizes, and patterns, allowing for versatile and customizable construction applications. Good interlocking design, ease of installation, flexibility and versatility, durability and repairability are the main features of interlocking blocks that poses benefits of it.

c. AAC Block

AAC (Autoclaved Aerated Concrete) blocks are lightweight and high-performance building materials used in construction. They are made from a mixture of fine aggregate, cement, lime, and water, with the addition of an expanding agent. The mixture is poured into molds and undergoes a process called autoclaving, where it is cured under high-pressure steam to create a cellular structure. Some of the beneficiary features contained by AAC block are lightweighted, good thermal and sound insulation, fire resistance, good strength and durability. They are commonly used in residential, commercial, and industrial construction for walls, partitions, floors, and other structural elements.

d. Concrete Beam Test

The concrete beam test, also known as the three-point bending test or simply the beam test, is a common laboratory test conducted to evaluate the flexural strength and behavior of concrete beams. This test provides valuable information about the load-carrying capacity, stiffness, and ductility of concrete under bending conditions. Concrete beams are prepared in the laboratory according to specified dimensions and mix proportions. A gradually increasing load is applied at the mid-span section of the beam until it reaches its maximum load-carrying capacity or until failure occurs. The load is typically applied at a constant rate specified in the testing standards. It helps to assess the structural performance of concrete beams and determine their load-carrying capacities and deformation characteristics.

e. Concrete Mix Design

Concrete mix design is the process of determining the proportions of various ingredients, including cement, aggregates, water, and admixtures, to produce concrete with the desired properties and performance. It involves selecting the appropriate materials and determining their quantities to achieve the desired strength, workability, durability, and other desired characteristics of the concrete. The specific types of cement and aggregates are selected and proportioned using different calculation methods. Commonly used methods are ACI (American Concrete Institute) method, DOE (Department of Environment) method and IS (Indian Standard) method.
