Concrete Mix Design, Quality Control and Specification
This book promotes a general understanding of the process by which low variability concrete can be produced to a given requirement, and aims to present the simplest possible process of effective mix design and quality control. This new edition illustrates how the use of computers and high-tech testing equipment can reduce costs and improve efficiency in controlling both ordinary and high performance concrete.

For example, an Agency is to undertake a project to design and build a new maintenance facility for its fleet of buses (scope), at an estimate of $30 million (preliminary budget) over a three-year period of construction (schedule).
In large organizations, departments dedicated to quality assurance and to safety might assign specific individuals to assume responsibility for these functions on particular projects.
From the standpoint of construction contractors or the construction divisions of large firms, the planning process for construction projects consists of three stages that take place between the moment in which a planner starts the plan for the construction of a facility to the moment in which the evaluation of the final output of the construction process is finished.
Project management software is a computer program that serves to streamline the process of running a project from conception to completion, taking out many of the detailed steps that are usually required. Project management…….
AISC requires that fasteners or welds for end connections of beams, girders, and trusses be designed for the combined effect of forces resulting from moment and shear induced by the rigidity of the connection.
The AISC specification for allowable stress design for buildings includes three interaction formulas for combined axial compression and bending.When the ratio of computed axial stress to allowable axial stress f /F a exceeds 0.15, both of the following equations must be satisfied:
