10 Signs of Bad Concrete Pour

CivilJungle

Introduction of Signs of Bad Concrete Pour. Concrete is one of the most widely used building materials in our construction industry. It is very important that concrete should be pulled into the mould with proper precaution and care otherwise, we will not get the desired strength of concrete. What Is Concrete?

Effect of segregation and bleeding on quality of concrete

Construction Cost Estimating

Segregation in concrete: Segregation means the detachment of ingredients in concrete. In concrete, the following types of segregations mainly occur:- 1. Detachment of coarse aggregate from the concrete mixture, 2. Detachment of cement pastes from the concrete throughout its plastic phase.

What Are Differences Between Shear Slump and Collapse Slump in Slump Test?

CivilJungle

Shear slump indicates that the concrete is not compacted. It may undergo bleeding and segregation so shear slump is undesirable for the durability of the concrete. If we get a shear slump, concrete is not acceptable due to lack of cohesion. It causes bleeding and separation. What Occurs During a Slump?

Tips to reduce bleeding in concrete

Construction Cost Estimating

Concrete is formed by mixing cement, fine aggregates and course aggregates. Bleeding in concrete is one of the vital issues. Bleeding means a type of segregation, in which water emerges out of concrete. or more, the bleeding channels will be continuous. Impacts Of Bleeding: 1.

How to prevent segregation of concrete

Construction Cost Estimating

Definition of Segregation of Concrete? Major components of concrete are cement, sand, aggregate, and water. Normally, a coating is made to concrete aggregate with cement and sand for developing the consistent mass disjointing of these constituent materials of concrete from each other. Type of segregation: 1.

What Is a Concrete Surface Retarder | Types of Retarders | Advantages & Disadvantages of Retarder in Concrete

CivilJungle

What Is a Concrete Surface Retarder? Surface retarders, also know surface “deactivators,” are applied to fresh concrete to chemically delay the set of the surface mortar. Unlike concrete set retarders, they allow the rest of the concrete to cure normally , without affecting the setting rate or strength gain.

Properties and benefits of self compacting concrete

Construction Cost Estimating

Self-consolidating alias self-compacting concrete is an extremely flowable type of concrete that does not need vibration for setting and compaction. It is a fully engineered concrete with greater fluidity. The strength is enhanced because of superior compaction and uniformity of concrete. Advantages of SCC: a.
