Sieve Analysis is a common method adopted to measure the grain size distribution of an aggregate which is termed as gradation. It is often used in civil engineering and material testing field. This analysis can be done both in fine and coarse aggregates. Aggregates having mean grain size which are less than 4.75 mm are…
Grout meaning is the process of injecting a fluid material into cracks, voids and fissures to fill them. It is a thin mortar used to seal joints between tiles, masonry units or rock constructions. Grouted meaning the past tense of grouting, referring to something that has undergone the grouting process. What is grouting? Grouting meaning…
Live loads or otherwise called super imposed loads are one important type of loading. To be considered by the engineer while designing a structure to ensure their safe design. Loads are the forces that may cause stresses, deformations, displacement and accelerations on a building. A structure or building component may be subject to various types of loads….
The sieve analysis Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, dividing the sum by 100. Sieves sizes are: 150-μm, 300-μm, 600-μm. The foundational layers beneath impressive infrastructure first begin with properly graded aggregates like gravel,…
Sieve analysis is a crucial process in determining the particle size distribution of coarse aggregates used in construction projects. The IS code for sieve analysis of coarse aggregate is IS 2386. The Indian Standard (IS) code provides guidelines for conducting sieve analysis to ensure consistent and accurate results. Importance of Sieve Analysis Coarse aggregates, such…
The trapezoid volume formula utilizes the fact that while the bases are unequal trapezoids at parallel orientations, the height remains perpendicular. By taking the average area of the two bases and multiplying by the height, you can calculate the overall volume. Specifically, V = 1/2 x h x (B1 + B2), where B1 and B2…
Graded coarse aggregate refers to the determination of the particle size distribution. They are sorted into groups by passing through a series of stacked sieves with progressively smaller mesh openings. The sieve sizes and percentage of aggregates falling into size fractions are key to the selection and performance of aggregates for different uses. Coarse aggregates…
Graded aggregates are aggregates that have been specifically sorted by size into appropriate classifications. The sorting of aggregates by size is known as grading. A well or properly graded aggregate will have a range of particle sizes that allow for strength, workability, and other properties needed for construction applications. Graded aggregates are used extensively in…
Staircase Equation – also known as the Stairway Formula is an important underlying mathematical formula on which the most essential architectural features allowing circulation within multi-story buildings, staircases rely on . At its core, the staircase equation establishes clear geometrical relationships between components like step depth, height, and number that impact aesthetics, functionality and safety….
