The main component, cement gel, is deposited in water-filled space within the visible boundaries of a body of paste. Space filled with gel contains gel pores; space not filled by gel or other solid material is capillary space. Hygroscopicity of cement gel, and capillary pores, accounts for various aspects of the properties and behavior of concrete.

Jul 20, 2019· In this work, the physical and chemical effects of small amounts of THEED added to Portland cement were investigated. THEED can be used as an accelerator for the setting of Portland cement. The compressive strengths of standard test mortars moist-cured for 1, 3, 28 and 90 days were enhanced in some cases by the addition of THEED.
