Due to the smooth surface of the gypsum base material, no plastering work is required prior to the application of paint and other finishing materials. Together with the ability to build the wall without stiffener up to 10 meters height, there is a significant cost saving in terms of material and labor could be contributed when using 'JUMBO Gypsum Block' walling system.

The compressive strength of UCOS gypsum blocks at varying water concentrations is shown in Fig. 9, compared to the gypsum flow casting blocks (a/g = 0.60 – GFM). 95% confidence intervals for the mean are shown. The compressive strength of UCOS gypsum blocks increased from three to four times when compared to the flow casting blocks one.
Gypsum block is a massive lightweight building material composed of solid gypsum, for building and erecting lightweight, fire-resistant, non-load bearing interior walls, partition walls, cavity walls, skin walls, and pillar casing indoors. Gypsum blocks are composed of gypsum, plaster, water and in some cases additives like vegetable or wood fiber for greater strength.
Gypsum blocks were available in 3-inch, 4-inch, and 6-inch thicknesses. The individual blocks had a height of 12 inches and a length of 30 inches. The product was available with either a solid core or with hollow tubes that ran the length of the block. The blocks were installed in a running bond pattern similar to concrete blocks.
if British Gypsum components are used throughout, and the Company's fixing recommendations are strictly observed. Any variation in the specifications should be checked with British Gypsum. Wall construction: 100mm medium density concrete blocks (minimum 120kg / m 2) Plasterboard fixing method: DriLyner BASIC using Gyproc Dri-Wall Adhesive
Gypsum blocks: cheap and simple. Gypsum blocks are often used as simple indicators of irrigation events. Gypsum blocks measure the electrical resistance of a block of gypsum as it responds to changes in the surrounding soil. The electrical resistance is …
The number and depth of gypsum blocks are determined by the specific crop. For deep rooted plants, we recommend three points; the lowest point of the root system, midway, and near the surface. The blocks should be left undisturbed. To read a block, connect the blocks' leads to the KS-D1 meter, press the READ button, and read the display.

Sep 24, 2020· 0.64. Fine Sand. cu.m. 0.054. This is a construction material breakdown guide and you should be able to get a rough estimate (close to actual) materials breakdown. 4″ is used in the concrete hollow block as it is the typical indoor CHB wall size for partitions. Note that materials breakdown for 4″ and 6″ concrete hollow block is NOT the same.
Foreign gypsum block originated in the mid-20th century, tens of millions of the world's production meters, including France, the annual output of 17 million square meters, while the domestic late start, and the production-based hand, the current domestic production of about 3 million square meters, while China's building habits and structures ...
The thermal conductivity of gypsum plaster is 0.23 W / m * C, and the thermal conductivity of cement is 0.9 W / m * C. After analyzing the data, we can conclude that gypsum is a "warmer" material. This is especially felt if you hold your hand over the surface of the wall.

The use of gypsum block was very common for interior partitions for many decades. In the United States, the marketing for this tile was phased out by the mid-1970s. In Europe gypsum blocks are still widely used and are gaining popularity as a building material with very low emissions of volatile organic compounds, extremely low radiation values ...
Jul 29, 2009· Moisture meters routinely used in the field to determine the moisture content in gypsum wallboard are primarily designed and manufactured to measure the moisture content of wood. Often they are used to decide whether to replace wallboard by determining if moisture is qualitatively higher or lower than another location. Because the moisture meter is so widely used, it is necessary to establish ...
sites. At a normal site, a gypsum block may last 2 to 3 years, but in areas of frequent irrigation or high water table it may require annual replacement. Fig. 1. Electrical resistance block. One manufacturer produces a resistance block and meter which reads directly in centibars
