Abstract:
In one aspect, the present invention relates to a mortar composition having good flowability comprising cement, pozzolanic materials, fine aggregate materials, retarder and additives selected from anti-segregating additive, rheology modifier or a mixture thereof. In another aspect, the present invention relates to a lightweight mortar composition having good flowability comprising cement, pozzolanic materials, fine aggregate materials, retarder, air entraining additive, lightweight materials and additives which include anti-segregating additive and rheology modifier. According to the present invention, the fine aggregate materials have a particle size of less than 3.360 mm. The present invention further relates to the use of said mortar composition having good flowability for molding and construction work. The molded products obtained from the mortar composition having good flowability include load bearing parts and non-load bearing parts, namely, blocks, countertops, tie-columns, lintel, moldings, walls and floors.
Abstract:
The present invention relates to a cast-in-place wall construction method comprising the steps of: determining the wall line; forming kicker along the determined wall line; providing at least one of heat protection material or sound protection material or water protection material inside the formwork; installing the formwork along the wall line such that there is a gap between the two panels of the formwork or a gap between one panel of the formwork and a rigid body located on the opposite side of said panel; filling the binder into the gap of the formwork; leaving said binder to harden and to cure within the formwork; and removing the formwork. According to the invention, the filling of binder into the gap of the formwork is carried out by positioning an end of at least one binder filling tube above the slurry surface level at which the binder is to be filled, with at least one binder filling tube being moved vertically or horizontally or with at least one binder filling tube being moved both vertically and horizontally in a relative manner.
