A concrete road slab of reduced mass is characterised by: it has three composite layers: an upper rolling plate (1),intermediate (2) and lower (3),where the top layer (1) of not less than three% total plate thickness is concrete or netting concrete, or fibrobethone, or ferro-concrete...
A digital process chain connects the design of the elements, the integration of the building services and the fabrication data of the formwork. This research is demonstrated on the project Smart Slab, the first concrete slab using 3D printed formwork. The Smart Slab is around 70% lighter than ...
The test results were compared with other test data on high-strength and normal-strength normalweight concrete slabs and code predictions for slab strength. Normally, a reduction factor of 0.83 is recommended for lightweight aggregates by the ACI code. A similar reduction of 0.80 is suggested by...
A light-weight wall element having a concrete slab constituting the external layer (8) of the element. This slab is made by using the frame (2) and an L-shaped profile (7) attached thereto as a mould and casting concrete therein. The slab is reinforced with a ribbed steel lathing (9...
This method consists of confining a pool of a 3-wt% NaCl solution with a depth of 6 mm on the surface of a concrete slab with a thickness of ≥75 mm. Specimens were then placed in a freezer for 16–18 h at a temperature of −17.8 ± 2.8 °C. The samples were then removed ...
The paving slab, made of concrete, artificial stone or similar, as laid on paths, garage forecourts, courtyards and elsewhere, is of reduced weight so as to be more easily handled and transported. This effect is achieved by incorporating one or more cutouts (6) to form a hollow space, ...
Besides, the large self-weight of normal concrete also impedes efficient PC slab construction. Unlike normal concrete, ultra-lightweight engineered cementitious... S Kobayashi - 《Japan Concrete Institute》 被引量: 0发表: 2017年 Use of EPS Based Light-Weight Concrete Panels as a Roof Insulation ...
摘要：PROBLEM TO BE SOLVED: To provide a floor slab and the like made of lightweight concrete, which have high water resistance, are lightweight and obtain sufficient strength.SOLUTION: A road structure 3 comprises a floor slab 31, a water-resistant layer 33 and a pavement layer 35. The ...
hollow light weight concrete slab machine for cellular lightweight concrete wall panels 1.This production system is for the production of different types wall panels, such as foam concrete wall panel(CLC wall panel), GRC wall panel,gypsum hollow core...
We have been focusing on the manufacturing of machines for prefabricated (precast) concrete components, and provide the supporting service of a total solution. Our company receive more than fifty national technical patents and Participate in the formulation of nine national ...
