13 Types of Domes in Architecture – theconstructor.org
网页3. Crossed-Arch Dome. Crossed-arch domes are a kind of ribbed vault that is unique. The ribs that make up the vault are intertwined, making shapes like polygons or stars and leaving space in the middle. The designs heavily include geometry, with the octagon being one of the most common geometric motifs.

Compressive Strength of Concrete -Cube Test [PDF], Procedure, …
网页By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength ...
7 Major Stages in Water Treatment Plant – theconstructor.org

Concrete Slump Test for Workability: Procedure and Results
网页The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. The slump is carried out as per procedures mentioned in ASTM C143 in the United States, IS: 1199 – 1959 in India and EN 12350-2 in Europe.
Reinforced Concrete Slab Design Guidelines - theconstructor.org
网页Steps to be followed in the design of slab. Assuming suitable bearings (not less than 10cm), find the span of the slab between the centers of bearings. Assume the thickness of slab (take 4 cm per metre run of the span). Find the effective span which is lesser of (i) distance between centres of bearings, and (ii) clear span and effective depth.
