A cura interna já era utilizada na época romana. Por exemplo, o famoso edifício do Panteão foi construído, em parte, com betão curado internamente. A cura externa do betão, como a nebulização da superfície, atinge apenas a superfície do betão, enquanto que com a cura interna toda a microestrutura tridimensional do betão pode ser curada. O objetivo desta tese foi estudar o impacto da cura interna na resistência à compressão, resistência à tração/flexão e retração por secagem. O objetivo era também determinar quais os tamanhos de grão dos agregados leves que seriam os melhores para a cura interna. Nesta tese, a cura interna é feita com agregados leves. Os resultados dos testes obtidos mostraram que os melhores tamanhos de grão dos agregados leves para a cura interna são 0-2 mm e 2-4 mm. A utilização destes tamanhos permitiu produzir betão com propriedades mecânicas semelhantes às do betão normal, mas com uma redução significativa da retração por secagem.

Zewnętrzne utwardzanie betonu, takie jak zamgławianie powierzchni, obejmuje tylko powierzchnię betonu, natomiast dzięki wewnętrznemu utwardzaniu można utwardzić całą trójwymiarową mikrostrukturę betonu.
