Types and Causes of Concrete Deterioration

leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan- sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2). Steel corrodes because it is not a naturally occurring material. Rather, iron ore is smelted and refined to produce steel. The ...

Composition of cement

Iron, Fe 2 O 3: from from clay, iron ore, scrap iron and fly ash; Gypsum, CaSO 4.2H 2 0: found together with limestone; The materials, without the gypsum, are proportioned to produce a mixture with the desired chemical composition and then ground and blended by one of two processes - dry process or wet process. The materials are then fed through a kiln at 2,600º F to produce grayish-black ...

Properties of Cement- Physical Chemical - Civil

Aside from adding strength and hardness, iron oxide or ferric oxide is mainly responsible for the color of the cement. Alkalis The amounts of potassium oxide (K 2 O) and sodium oxide (Na 2 O) determine the alkali content of the cement. Cement containing large amounts of alkali can cause some difficulty in regulating the setting time of cement. Low alkali cement, when used with calcium chloride ...

Effect of insoluble residue on properties of Portland

01/08/2000  The effect of insoluble residue for each percentage as a cement replacement on normal consistency and setting times were presented in Table 3. The replacement of insoluble residue up to 7.0% did not change the normal consistency of cement. The required water for normal consistency was still the same and remains at 26.8%. This is due to the same particle size distribution of the insoluble ...

Effect of Water Impurities on Concrete Strength ...

Another salt that brings destructive effect on concrete is the lead nitrate. Other salts like sodium phosphate, sodium arsenate, sodium iodate and sodium borate result in the reduction of the initial concrete strength to a very lower degree. The sodium and potassium carbonates cause extremely large rapid setting in large concentrations. This results in the reduction of concrete strength. The ...

Effect of Chloride Attack on Durability of Concrete ...

White dealing with the durability aspect of concrete, the chloride effect on concrete is the most impor­tant factor as it causes the corrosion of reinforcement of concrete. The statistical studies have shown that more than 40% structures have failed due to the corrosion of reinforcement steel. Due to high alkaline nature of calcium hydroxide (pH value about 13) in concrete a protective oxide ...

What is the difference between grey and white cement?

Stabilized soil mixing plants and concrete mixing plants are suitable for the production of raw materials for engineering construction. Stabilized soil is mostly used in the base and subbase of roads. Concrete is used in civil engineering. Both of...

Secrets to Special Effects with Concrete Stains

01/06/2007  Secrets to Special Effects with Concrete Stains. Written by Susan M. Brimo-Cox on June 1, 2007. Decorative concrete artists have become quite creative in using acid stains, water-based stains, dyes and paints on concrete. Acid stains offer the most earth-like, weathered and warm colors. However, because of their iron

Rust Coloured Stains on the surface of Exposed Aggregate ...

of concrete. This document deals specifically with rust coloured stains created by “Ironstone” on the surface of Exposed Aggregate Concrete. Ironstone is the common term used to describe unstable aggregate (stone) particles that are rich in iron oxide minerals. These stones are generally dark grey to

Cement Types, Composition, Uses and Advantages of ...

We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.

The Properties and Effects of Manganese as an Alloying

The effect of manganese in improving the mechanical properties of steel depends on its carbon content. Manganese also reduces the critical cooling rate during hardening, meaning it increases the hardenability of steel. Its effect on hardenability is higher than other alloying elements. Hadfield steel is recognized for its ability to be work-hardened due to the addition of 10% to 14% of manganese.
