Fire and Concrete Structures

Concrete containing lightweight aggregates and carbonate aggregates retain most of their compressive strength up to about 1200 oF. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance.

Metric calculator for concrete

These Concrete Calculators provide the required quantities of cement and all-in ballast or cement, sharp sand and gravel required to give a defined volume of finished concrete. Both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete.

Masa Group

The slab press UNI 2000 is the heart of any plant for the manufacture of concrete slabs. In addition, dosing and mixing plants, take-off devices with direct washing units and storage systems as well as machines and equipment for slab refinement and packaging are required. Masa can offer the complete know-how for the production of concrete slabs.

Mechanical Properties of Polymer Concrete

Polymer concrete was introduced in the late 1950s and became well known in the 1970s for its use in repair, thin overlays and floors, and precast components. Because of its properties like high compressive strength, fast curing, high specific strength, and resistance to chemical attacks polymer concrete has found application in very specialized domains.

c20 c25 concrete

conventional grade-c20-c25-c30-concrete mix ratio | The four materials of water, cement, sand, and gravel are the most basic components of concrete. Secondly, we need to choose according to the purpose of the concrete. conventional grade-c20-c25-c30-concrete mix ratio, the following design methods are carried out.

Fireproofing Methods for Structural Steel

Also known as intumescent paint, this method provides fire resistance to structural steel members. One of the key benefits is that intumescent coatings will expand as much as 100 times the original thickness of the material, providing superior fire resistance by creating a buffer between the fire and the steel members.The coating will undergo a chemical reaction and expand when subjected to

Concrete Mix Design

May 17, 2017The grade of concrete is also denoted as C16/20, C20/25, C25/30, etc., which means Concrete Strength Class (C) the number behind C refers to Compressive strength of Concrete in N/mm 2 when tested with Cylinder / Cube. Remember : 1MPA = N/mm 2. Different grades of concrete :

Floor Deck

The deep profile allows a deeper and stronger pour of concrete therefore a higher slab depth is necessary, and very thick slabs can be achieved. As with all floor deck panels, the width allows for easy installation using male and style receptor connections. The galvanized finish is in stock in 18 gauge in a 25' length (36" wide).

Concrete Mix Design Guide

Volume of coarse aggregate per unit volume of concrete Nominal maximum size of aggregate, in (mm) Volume of oven-dry-rodded coarse aggregate per unit volume of concrete for different fineness moduli of fine aggregate 2.40 2.60 2.80 3.00 3/8 (9.5) 0.5 0.48 0.46 0.44 1/2 (12.5) 0.59 0.57 0.55 0.53

Properties of concrete

Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
