It is important to ensure your lawn aeration specialist has the proper licensing and qualifications to do the job and ensure you're adequately protected in case things go wrong.. The first step is to ask the company or the pro for this information. They should happily supply you with all the details and assistance you with verifying this info online with your state licensing agency.
Dynamic behavior of concrete. Object of investigation is aimed at ascertaining the dynamic properties of concrete and cementpaste specimens representing a model of the structural material and its adhesive component, respectively, and to attempt to provide a simple characterization of the physical behavior of these materials on a macroscopic ...
The paper presents a study on the use of cementbased sensors doped with carbon nanotubes as embedded smart sensors for static and dynamic strain monitoring of reinforced concrete (RC) elements. Such novel sensors can be used for the monitoring of civil infrastructures. Because they are fabricated from a structural material and are easy to utilize, these sensors can be integrated into ...
This aerator, which is controlled by a walking operator, is intended to be used by professional, hired operators in commercial applications. It is designed primarily for aerating large areas on wellmaintained lawns in parks, golf courses, sports fields, and on commercial grounds.
The Multiple Analysis Cement System (MACS II®) instrument performs static gel strength tests on cement slurry samples.. The MACS II instrument conducts these tests under simulated downhole pressure and temperature conditions to determine the Zero Gel Time/Transition Time (SGS/Time) of oil well cement.
