Abstract: The present invention provides a concrete vacuum tube segment for a hyper-speed transportation system using ultra-high performance concrete (UHPC) and a manufacturing method thereof. A concrete vacuum tube segment for a hyper-speed transportation system can be easily manufactured using UHPC, in which shrinkage and structural cracking do not occur due to mixing a binder and a short fiber to secure airtightness on the basis of a maximum fill theory, and accordingly, shrinkage of the concrete vacuum tube segment can be reduced even in a partial-vacuum state in which the magnitude of drying shrinkage is very small and quick drying occurs; when mixing the UHPC, an antifoaming agent is mixed and a circular vacuum pump is used to remove generated entrapped air to minimize the entrapped air; and a capsule-type crack healing material, which is able to repair fine cracks, is compacted to secure airtightness of the concrete vacuum tube segment.

Abstract: A system and a method for concrete production is disclosed. In some implementations, the method comprises the steps of mixing of a calcium carbide residue (CCR) and ordinary Portland cement (OPC) to produce a CCR-OPC blended concrete, incorporating the CCR-OPC blended concrete in its fresh or hardened state to a carbonation chamber for accelerated carbonation curing, and producing a carbonated CCR-OPC blended concrete after the accelerated carbonation curing. The CCR-OPC blended concrete is exposed to a carbon dioxide (CO2) gas to promote a plurality of properties. The system includes a blending module and a carbonation chamber. The blending module mixes CCR and OPC to produce a CCR-OPC blended concrete, and the carbonation chamber performs accelerated carbonation curing of the CCR-OPC blended concrete in its fresh or semi-hardened state to produce a carbonated CCR-OPC blended concrete.

Abstract: A concrete comprises in relative parts by weight: 100 of Portland cement; 0.25 to 9 of a defoamer; 0.001 to 6 of a surfactant; 0 to 230 of coarse gravel and/or fine gravel and/or shear enhancers; 0 to 85 of sand; 0 to 60 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size less than 15 micrometers; 0 to 80 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size between 15 to 88 micrometers; 0.3 to 18 of a water-reducing superplasticizer; 0 to 14 of polyethylene fibers; and 5 to 40 of water. An air mixing process using a tightly sealed mixing tool is used to thoroughly mix the constituents of the concrete before adding the water for curing. By adjusting relative parts in the composition, concretes of high and ultrahigh performance can be achieved efficiently.
