Portland blast-furnace slag cement, or Blast furnace cement (ASTM C595 and EN 197-1 nomenclature respectively), contains up to 95% ground granulated blast furnace slag, with the rest Portland clinker and a little gypsum. All compositions produce high ultimate strength, but as slag content is increased, early strength is reduced, while sulfate ...
Ordinary Portland Cement(OPC) is the most widely used cement in the construction world. It is the basic ingredient for producing concrete, mortar, stucco, and non-specialty grouts. Ordinary Portland Cement is graded based on its strength. The grade indicates the compressive strength of the mortar cube that will be attained after 28 days of setting.
Portland cement shall conform to the requirements of the following cited specifications except as noted. 1. Requirements Cement Specifications Air-Entraining Portland Blast-Furnace Sl ag Cement AASHTO M 240, Type IS-A Air-Entraining Portland Cement AAS HTO M 85, Type IA or IIIA
In addition to normal Portland cement, rapid hardening Portland cement, high alumina cement and calcium sulphoaluminate cements have also been used in foamed concrete to reduce its setting time and improve the early strength . Using geocements and alkaline Portland cement is reported to improve the fire resistance of foamed concrete .
Type I/II – Our Type I/II Portland cement meets the requirements of both Type I and Type II, including strength and composition requirements, and can be used in projects where either type is required. More cost-effective than storing both types, Type I/II can be used on most concrete construction projects, including those that expose the concrete to harsh environmental conditions.
QUIKRETE® Portland Cement (No. 1124) complies with current ASTM C150 and Federal Specifications for portland cement. Can be mixed with aggregate and other ingredients to make concrete mix, mortar mix, and base coat stucco. Available in Type I, Type I/II and Type III. Available in: 47lb. bags - …
ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
Engineers and construction professionals often specify a certain type of portland cement to meet special requirements of conditions. Cement types are defined by a variety of standards and specifications. Portland cements conform to the American Society for Testing and Materials (ASTM) C150 Standard Specification for Portland Cement and Canadian ...

May 06, 2020· The cement produced is differentiated by the distribution of these materials in its chemical composition, as well as the finishing products. The distinct types of portland cement are defined through ASTM C150-20: Standard Specification for Portland Cement, which distinguishes them by purpose. The standard types of portland cement are:
Preparation. CEMEX's Type N Masonry Cement, Type S Masonry Cement and Type M Masonry Cement are proportioned with sand meeting ASTM C-144, according to Table 4, and will produce mortar meeting the requirements of ASTM C-270 under the proportion specifications.
CEMEX guarantees Victor Portland Cement, when shipped from our mill or terminals, to meet the current requirements of ASTM C-150, (Standard Specification for Portland Cement). Since we have no control over other ingredients mixed with this product or final application, we …
During cement hydration CaO in conjunction with SiO 2, Al 2 O 3, and Fe 2 O 3 leads to hardening of Portland cement due to the formation of calcium aluminosilicates and aluminoferrite hydrate. With Portland cement, an increased presence of MgO (greater than 2%) may be detrimental to the soundness of cement, especially at late ages.
Ternary cementitious mixtures (mixtures with portland cement, GGBFS, and fly ash) will be allowed for Class CP Concrete provided that the minimum portland cement content is 50%. The maximum amount of fly ash substitution in a ternary blend will be 20%. Substitution rates will be at a 1:1 ratio.
For instance, portland cements and blended hydraulic cements for concrete in the U.S. conform to the American Society for Testing and Materials (ASTM) C150 (Standard Specification for Portland Cement), C595 (Standard Specification for Blended Hydraulic Cement) or C1157 (Performance Specification for Hydraulic Cements).
Updated June 18th, 2020We generally use hydraulic cement in our construction which is best known as Portland cement. Cement properties vary in different "types of cement" because of different percentage of "cement ingredients". To construct economical concrete structures or cementitious product it is essential to know the properties of cement. Cement properties can be categorized […]
Mortar cement (ASTM C1329, ref. 4j) is a hydraulic cement similar to masonry cement, with the added requirement of a minimum bond strength requirement. Blended hydraulic cements (ASTM C595, ref. 4g) consist of standard portland cement or air-entrained portland cement (denoted by -A) combined through blending with such materials as blast furnace ...
Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. 'Heat of hydration' is the term used to describe the heat released when cement reacts with water during the ...
