ESTIMATION OF COMPRESSIVE STRENGTH OF PUMPABLE …

Pumpable concrete is conveyed under pressure through a hose or a pipe. Now-a-days it is widely used in infrastructure construction practices as it saves labour, cost and time. The compressive strength of concrete at 28 days is a commonly used criterion in producing concrete. The tests on the compressive strength are complicated and time consuming.

Different Grades Of Concrete | Based On IS, American

Grades of Concrete Different nations have their own grade of concrete. We will discuss some of them. 1.1. Grades of Concrete Based on IS The grade of concrete is the minimum strength that the quality-controlled concrete posses after 28 days of construction. There are different grades of concrete like M15, M20, M25, M60, etc.

Mix Design and Pumped Concrete - Civil Engineering Portal

A pumpable concrete, like conventional concrete mixes, requires good quality control, i.e., properly graded uniform aggregates, materials uniformly and consistently batched and mixed thoroughly. Depending on the equipment, pumping rates will vary from 8 to 70 m3 of concrete per hour.

CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.

(h) Method of placing Concrete on Site = pumpable concrete (ii) Material testing data (determined in the laboratory) (a) Specific gravity of cement = 3.15 (b) Specific gravity of FA = 2.64 (c) Specific gravity of CA = 2.84 (d) Aggregates are assumed to be having surface dry conditions. (e) Fine aggregates are confirmed to Zone II of IS – 383

Proper Methods for Placing Concrete Good Construction Practice

Concrete placement is an important process in the construction that determine the success of the structure and its life. Technical and environmental Concrete placement is an important process in the construction that determine the success of the structure and its life. Technical and environmental conditions are taken into strict consideration while placing the concrete.

Factors Affecting Pumping of Concrete - Civil Bull

Jul 18, 2021 · They have been used successfully on many pump jobs, especially for high rise construction. However, the water reducer will not by themselves make an un-pumpable concrete into pumpable without proper grading of the aggregates. Fly ash. Fly ash is a fine material that can be added to concrete either as an admixture or a partial cement replacement.

Seven Must-Use Concrete Admixtures (Additives)

Aug 16, 2021 · Concrete Admixtures: Air-Entrainment. Air entrained concrete can increase the freeze-thaw durability of concrete. This type of admixture produces a more workable concrete than non-entrained concrete while reducing bleeding and segregation of fresh concrete. Improved resistance of concrete to severe frost action or freeze/thaw cycles.

Major Problems in Concrete Pumping Works: How to Avoid

Major Problems in Concrete Pumping Works. 1. Blockage of Concrete Pump. Blockage can occur due to numerous bends in the pipeline, too sharp or too wide turns, gap-graded aggregate, and failure to clean and maintain the pipeline after each concreting work. High water-cement ratio and long waiting-time at construction site during which concrete

Flowable Fill Concrete - Properties, Uses, Benefits - The

🕑 Reading time: 1 minuteFlowable fill concrete is a self-compacting cementitious slurry consisting of a mixture of fine aggregate or filler, water, and cementitious material which is used as a fill or backfill in lieu of compacted-soil backfill. This mixture is capable of filling all voids in irregular excavations and hard to reach places (such […]

What Is the Difference Between Lean Concrete & Flowable

Lean concrete and flowable concrete are terms used to describe low-grade concrete slurry that is used in a variety of construction projects. In some ways the two terms are interchangeable, both describing concrete made with lesser ingredients, but there are some differences in how the two are used.

Why Pump Concrete? | Construction Equipment

Sep 28, 2010 · A concrete pump places concrete faster and more accurately with less labor than any other method. A job that would take five men two and a half hours to pour would only take three men one hour to pump. Contractors who pump concrete consistently report labor savings of 50 percent compared to truck dumping.
