Base cement reinforced to post made of woodMOREAU MARIUS
Stabilizing clays with cement or lime can improve subgrade properties at a lower cost than either removing and replacing material or increasing the base thickness to reduce subgrade stress. The clay soil stabilization mechanism for the calcium-based stabilizers portland cement and lime is reviewed. ...
The tibial cement-pressurising device eliminated regional differences in stiffness seen with other cementing methods. Elimination of these differences by using this device should reduce micromotion and the incidence of aseptic loosening of tibial base plates in total knee arthroplasty. 展开 ...

Silicon-Base Sealer RoekoSeal (Roeko, Langenau, Germany) is a polydimethylsiloxane-based root canal sealer. One in vitro study comparing it with eugenol-based Sealapex or Ca(OH)2-based Kerr's Pulp Canal Sealer concluded that RoekoSeal was less cytotoxic.8 It has adequate solubility properties....
A glass ionomer cement composition comprises poly(vinyl phosphonic acid) dissolved in its own mass of water; and (in treble the total mass of the solution) a powder, being glass or MgO or a cermet. The powder has to be deactivated so that the setting reaction with the acid is not too ...
product. In Japan, most demolished concrete is downcycled as road base materials, turned into hibernating stock, or landfilled; thus, there is an almost invisible recycling flow to concrete aggregates. Fig. 1: Cement and concrete cycle and associated-CO2fluxes in Japan in 2019....
For some solid additives, the addition may be expressed as a volume ratio to the cement or as a volume ratio of the total blend. In many cases, the base blend includes significant components that are not cement, such as fly ash. Fly ash is a special case where the blend is specified ...
When make C50 concrete, it should choose the suitable material according to relative technology rule and confirm the suitable mixing technology base on enough test data. To make sure the fluidity of concrete can meet with the requirements of engineering, the strength of concrete should...
