"expansive material" is a correct and usable phrase in written English.
It can be used in various contexts, such as in technical or scientific writing, literature, or everyday conversation. Example: "The scientists used an expansive material to create a balloon that could withstand extreme temperatures."
Fly ash may inhibit the autogenous volume expansion of concrete with MgO expansive materials, and the effect became more significant with the dosage increase of fly ash.
The micro-expansion caused by the additive MgO expansive materials filled the pores of paste and made the structure denser, and might compensate the shrinkage of concrete, decrease the cracking of concrete works and improve the durability of concrete.
The paper concludes with some considerations on the capability of highly expansive materials to provide a significant degree of homogenization upon hydration.
The landsurface bears cracking patterns similar to those produced by multiple episodes of wetting and drying in expansive materials on Earth.
The results showed that the autogenous volume deformation of the concrete increased with the curing ages and the content of MgO expansive materials.
The autogenous volume deformations of concrete with MgO expansive materials and fly ash cured in different ages were measured, and the morphologies of it were observed through scanning electron microscope.
Hydraulic and mechanical constitutive laws suited to expansive clay materials have been chosen for the analyses with all the parameters determined independently of the in situ test.
A series of specimens was additionally produced using expansive admixture (binding material replacement ratio-1%) and fiber (binding material × 0.2) and examined for the comparative evaluation of admixture materials used for reducing cracks of LMC.
The four CD's of "Q" divide the work into big-band sides he arranged, conducted or both (on a disc called "Jumpin' in the Woodshed"), selections from soundtracks ("Gone Hollywood"), famous numbers by famous people he has produced ("Hit Man") and finally a nimble, expansive compilation of material released under his name ("The Dude Throws Down").
