It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Among other qstm, the initial and final time of set are influenced by: This reaction combines water with cement forming chemical compounds, increasing the strength of the material and changing it from a plastic, moldable material to a solid capable of withstanding substantial loads.

Are you sure you want to empty the cart? Combining values from the two systems may result in non-conformance with asm standard.
