ppt on light weight aggregates

Lightweight aggregatesLightweight aggregates. In the UK the most commonly used lightweight aggregate is LYTAG, a sintered fly ash, also known as pulverised fuel ash (pfa). Other aggregates, made from a variety of raw materials, are shown in the Table below.Lightweight concrete - PORAVER expanded glassIn addition, light weight concrete is non-combustible, sound-absorbing and particularly economical. With Poraver® expanded glass granules as an aggregate, lightweight concrete becomes a purely mineral and ecological building product which can simply be recycled if needed.High Density Concrete: Types and Properties | Concrete ...Aggregates to be Used in Shielding High Density Concrete: For making shielding concrete heavy weight aggregate having a specific gravity between 3.5 to 4.0 is needed. There are many aggregates whose specific gravity is more than 3.5 for making a heavy weight concrete. Some of natural commercially used aggregates are as follows: 1. Barite . 2.Advantages and Disadvantages of Lightweight Concrete ...Jun 29, 2020· Specific types of lightweight aggregates make varying forms of lightweight concrete. These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This composition makes AAC highly suitable for pre-casting and reshaping.

STUDY OF LIGHTWEIGHT CONCRETE BEHAVIOUR

characteristic of this lightweight aggregate is its high porosity which results in a low specific gravity [17]. The lightweight aggregate concrete can be divided into two types according to its application. One is partially compacted lightweight aggregate concrete and the other is the structural lightweight aggregate concrete. The partially ...Structural Lightweight Concrete - ESCSIoverview Structural lightweight concrete made with rotary kiln produced structural lightweight aggregate solves weight and durability problems in buildings and exposed structures. Structural lightweight concrete has strengths comparable to normal weight concrete, yet is typically 25% to 35% lighter. Structural lightweight concrete offers design flexibility and substantial cost savings by ...High density concrete | Heavy weight aggregate | LKAB ...When using only MagnaDense as a high density aggregate, concrete with densities up to 4.0 t/m 3 is achievable. Mixing MagnaDense into concrete with other aggregates allows you to produce even heavyweight concrete with densities up to 5.0 t/m 3. With the correct mix design, high-density concrete can still achieve good workability.

Expanded clay (left) and expanded shale (right). (69793) T 27). The range of particle sizes in aggregate is illustrated in Fig. 5-4. The aggregate particle size is determined by using wire-mesh sieves with square openings. The sevenLecture 4. Aggregates4.2.2 Manufacturing of lightweight aggregates (6) Manufactured lightweight aggregates are produced by expanding some raw materials in a rotary kiln, on a sintering grate, or by mixing them with water. The most common lightweight aggregates are pumice, scoria, expanded shale, expanded clay, expanded slate, expanded perlite, expanded slag and

Lightweight Concrete - What Is Lightweight Concrete And ...

A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.What is Lightweight Concrete? -Types, Uses and AdvantagesLightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).Download Lightweight Concrete Seminar Reports, abstract ...Download Lightweight Concrete seminar reports, ppt, pdf, Lightweight Concrete Seminar Topics, Abstracts, Full Documentation, Source Code. 123seminarsonly. ...

LIGHT WEIGHT CONCRETE 2. Definition: Concrete having a 28-day compressive strength greater than 17 Mpa and an airdried unit weight not greater than 1850 kg/m³. Composition: Similar to normal concrete except that it is made with lightweight aggregates or combination of lightweight and normal-weight aggregates.Performance of Light Weight Concrete using Fly Ash Pellets ...aggregate in developing light weight concrete of M40 grade to study the workability and strength properties. MATERIALS AND METHODS Cement Ordinary Portland cement Zuari-53 grade conforming to IS: [6] was used in concrete. The physical properties of the cement are listed in Table 1.Flashag – New Lightweight Aggregate for High Strength and ...KEYWORDS: fly ash, aggregate, lightweight, concrete, high strength, shrinkage . ABSTRACT . A new patented lightweight aggregates is tested. This type is given the name Flashag. The only solid raw material used to manufacture these aggregates is fly ash. The aggregates are sintered but not pelletized and the process is easy and inexpensive.Chapter 2 Asphalt and Asphalt Paving MaterialsAGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.Structural Lightweight Concrete - ESCSIoverview Structural lightweight concrete made with rotary kiln produced structural lightweight aggregate solves weight and durability problems in buildings and exposed structures.
