ASTM C806-95 Standard Test Method for Restrained Expansion of Expansive Cement Mortar
This test method covers the determination of length changes of expansive cement mortar, while under restraint, due to the development of internal forces resulting from hydration of the cement.
Cat: Standards and Guidelines

ASTM C845-96 Standard Specification for Expansive Hydraulic Cement
This specification covers hydraulic cements that expand during the early hardening period after setting.
Cat: Standards and Guidelines


ASTM C618 - Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use as a Mineral Admixture in Concrete
A table with chemical and physical requirements listed in the ASTM C618 specification for the three classes of pozzolans: Class N, Class F, and Class C.

Alkali-Silica Reaction and High Performance Concrete
Answers the question if high-performance concrete is susceptible to alkali-silica reaction. The paper contains details on the alkali-silica reaction mechanism and the factors influencing it as well as an overview on available test methods (i.e. ASTM C1260 and C227). Besides an abstract the fulltext is available as PDF (24 pages, 1,3 MB).
