TYPES OF CONCRETE MIX DESIGN

The Constructor

Nominal Mixes In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates. These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. No control testing is necessary reliance being placed on the masses of the ingredients.

ACI certification builds concrete wisdom

GCP Applied Technologies

If you visit the American Concrete Institute's (ACI) website , you'll soon learn why becoming ACI-certified for testing concrete is important, and necessary for building sound, safe, sustainable structures. Why, then, is ACI certification so important in such a controlled—the lab is kept at an ideal 70°F—environment?

RESIDENTIAL BUILDING SITE PLANNING

The Constructor

The requirements of site for buildings with different occupancies are different. So all the buildings proposed for different purposes have different requirements and thus different considerations for their site selection. The site should be in fully developed area or in the area which has potential of development.

Fineness Modulus of Fine Aggregate | Fineness Modulus of Coarse Aggregate | Sieve Analysis of Fine Aggregate | Sand Zone Classification

CivilJungle

Fineness Modulus of Fine Aggregate: The sand fineness module (fine aggregate) is an index number describing the mean size of sand particles. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. So, we require all sizes of sieves in the coarse aggregate measurement.

REINFORCEMENT CORROSION-CAUSES & PREVENTION

The Constructor

The composition of mild steel varies along its length and potential anodic (more negatively charged) and cathodic (positively charged) sites can be set up at various points. This is an expansive reaction leading to eventual spalling of concrete cover and reduction in the area of the steel at the anodic site. The above fig.
