In this article, the Compaction Factor Test is discussed which is used to calculate the compaction factor, and to know more about workability. Compaction Factor Test Objective: To calculate the compaction factor, and to know more

Shotcrete: Why to Use

June 3, 2017 TeamCivil Concrete, Types

Why Shotcrete a. Importance of proper application Properly applied shotcrete is a structurally sound and durable construction material which exhibits excellent bonding characteristics to existing concrete, rock, steel, and many other materials. It can have

Effect of Age on Concrete Strength

May 30, 2017 TeamCivil Concrete, Properties

Effect of Age on Concrete Strength The strength versus gel/space ratio relationship has a general application because the amount of gel present in the cement paste at any time is itself a function of age

Water in Concrete Water is a necessary component of all hydraulic concrete. It is usually used in amounts of 25–50 weight per cent of the cement. It has two engineering purposes: to enable (a) proper

Rebound Test: Equipment – Operation

May 21, 2017 TeamCivil Concrete, Tests

In this article, the Rebound Test (schmidt hammer test) is outlined. The Swiss engineer Ernst Schmidt, first developed a practicable rebound test hammer in the late 1940s, amd modern versions are based on this. Figure 1 shows the

Classification of Aggregates

May 16, 2017 TeamCivil Concrete, Materials

In this article named “Classification of Aggregates”, the general classification of aggregates is described. General Classification of Aggregates Aggregate size applied in concrete can vary from less than one-tenth of a millimetre to tens of

Concrete Aggregates

May 12, 2017 TeamCivil Concrete, Materials

Concrete Aggregates Aggregate is the most voluminous component of concrete. Depending on the desired concrete properties, primarily strength but also durability and other properties, the mass of aggregate in concrete represents about 3.5 (for high-strength) to

Visual Defects of Concrete
