土壤样品制备

样品制备

Testing of soil for building construction or of any structure should always be the first step in planning to ensure the suitability of soil properties. 的 soil will need to handle the stress emanating from the structure and any unreliable or undetermined tests can be catastrophic to its ultimate life span and safety. 的 specific types of tests needed will depend on the properties of the soil and the type of construction project. Thorough understanding of soil properties can even sometimes enable engineers to build in potentially problematic areas.

In order for soil samples to be correctly and thoroughly tested in the lab, they must first be collected and processed. 的 soil samples need to be dried, ground and sieved before they are analyzed. A number of different tools are employed for proper preparation of the soil samples for testing. Soil grinders are used to prepare samples for evaluation of grain sizes, 界限含水量 and other tests. Soil mixers are designed to mechanically mix the sample with an in situ binder. 的 process breaks up the soil, injects a binder at low pressure and mixes the binder with the soil.

洪堡 offers high-quality equipment and accessories for accurate preparation of soil samples.

的 快速土壤处理机 simplifies preparing soil for compaction tests by producing five-point moisture density test results five times faster than any other available method.

的 土壤磨床 prepares samples to a designated particle size for accurate, 可重复的结果, can can grind a one-point sample in 15 seconds.

的 电动圆盘磨机 是否用于全局采样. 的 grinding mill head and plates are made with quality materials for durability and long service life. 的 grinding mill head is easily removed and disassembled for cleaning.

的 Hand-Operated Disk Grinding Mill mounts to a bench top with an integral c-clamp for fast grinding of samples. 的 mill head is easily disassembled for cleaning without any special tools needed.

的 洪堡实验室混合器 (5L – 5.3 qt.) provides testing labs with a higher quality than a typical lab mixer. 的 mixer features a clear safety cover for sealed mixing and allows for materials to be added to the mix via a port at the top of the mixer.

的 5-Qt. 混合机 thoroughly blends, mixes and aerates all ingredients for a consistent, predictable result. Includes a stainless steel bowl, wire whip, dough hook and aluminum flat beater.

的 砂浆搅拌机 (5L – 5.3 qt.) is a high-quality ASTM mixer that provides a more durable and lower cost alternative to the Hobart mixer. It features a robust design and works especially well for efficient mixing of cement pastes and mortar.

沉重的瓷器 土壤砂浆 is ASTM D421 compliant and specifically f或使用 with our H-4258 土壤杵.
