摘要： There is described a method of operating a concrete mixer truck having a rotary drum configured to receive fresh concrete and an on-board computer. The method generally having: performing an unloading operation including unloading a first portion of the fresh concrete from the drum at a job site, a second portion of the fresh concrete remaining in the drum as return concrete subsequently to the unloading operation; the computer acquiring a first signal indicative of a presence of fresh concrete in the drum; the computer acquiring a second signal indicative of termination of the unload operation; the computer activating an indicator perceivable by a driver of the concrete mixer truck contingent upon receiving both the first signal and the second signal, the indicator signalling a presence of return concrete in the rotary drum to the driver.

摘要： A spraying system and method is provided for more efficiently accessing the interior of a container having an access opening to the container that is offset from or in angular relationship to the center and/or rotational axis of the container to contact the interior walls and surfaces of the container with a medium, such as a liquid, mixture, solution or suspension. The spraying system and method includes a non-linear boom that is elevated by a support structure, where the non-linear boom includes at its front end a plurality of spray nozzles. In one example, the support structure is a movable support structure that includes a guide mechanism where the guide mechanism is mounted on the moveable support structure at an angle relative to the surface supporting the moveable support structure to allow access to the interior of the container.

摘要： Disclosed are exemplary process and system for managing a mix design catalog of a concrete producer that involves collecting slump curve data obtained during in-transit monitoring of delivered concrete loads made from a plurality of various mix designs, wherein each mix design is identified by a different identification code (regardless of whether components are different), clustering slump curve data having same movement characteristics according to assigned strength value, and selecting a mix design to produce, to display, or both to produce and to display, from among the two or more slump data curves of individual mix designs within the same data curve cluster. The selection is based on same movement characteristic and assigned strength value, and at least one factor relative to cost, performance, physical aspect, quality, or other characteristic of the concrete mix or its components. Exemplary methods for generating new mix designs are also disclosed.

摘要： The invention relates to a method and/or system of collecting and treating waste or residual uncured concrete so that it can be reused in various applications. Broadly, the method involves collecting residual uncured concrete from multiple sources and treating each batch of uncured concrete with a calculated amount of an inhibitor formulation to inhibit the curing or setting time of the batch for a predetermined time period to enable the separately sourced batches of uncured concrete to be combined into a single aggregated batch of uncured concrete for reuse. The invention enables residual or waste uncured concrete from multiple jobs or sources to be aggregated and stabilized to the same level so that the combined batch remains uncured for the desired time period in order to allow for the effective reuse of the otherwise wasted concrete. The aggregated batch of uncured concrete can be treated with a calculated amount of an activator formulation to advance the setting time of the batch as required for its reuse.

摘要： Described are a method and system for minimizing errors in the manufacture or management of aggregate-containing construction materials such as concrete. Aggregates used for making concrete are stored or weighed in dry bulk bin type hoppers, and conveyed from these hoppers into mixer drums which batching or mix the concrete. The hoppers or conveyor belts may contain sensor probes for measuring moisture levels in the aggregate. These sensor probes require calibration from time to time, but time and expense are required for proper calibration, leading to habitually erroneous moisture level data used in the industry on a daily basis. The present inventors believe that the smallest inaccuracies in aggregate moisture level readings can have profound effects on the properties of the resultant concrete product. To confront this problem, the present inventors discovered that the inaccuracy of these aggregate moisture sensors, as used for evaluating the aggregate as a dry bulk material, can be detected and even addressed through the use of slump monitoring systems to evaluate the concrete slurry mix prepared from the aggregates.

摘要： The present invention provides a method and system for detecting hardened concrete buildup in a mixer drum which is substantially devoid of plastic concrete. An exemplary method involves monitoring the hydraulic pressure required to rotate the drum through at least two successive rotations at constant speed, using a hydraulic pressure sensor on hydraulic charge side, discharge side, or preferably both sides of the hydraulic motor which turns the mixer drum; and detecting when the pressure/time data curve indicates eccentric behavior of the mixer drum, whereby an alarm or other indication is provided to confirm that the hardened concrete buildup in the truck is not acceptable. The buildup detection method and system of the present invention does not require the use of an automated slump monitoring system, but can be implemented in combination with such systems with favorable results a nd advantages.
摘要翻译：本发明提供了一种用于检测基本上没有塑性混凝土的搅拌筒中的硬化混凝土堆积物的方法和系统。一种示例性方法涉及使用转动搅拌筒的液压马达的液压加载侧，排出侧或优选两侧上的液压传感器监测通过至少两个连续转速以恒定速度转动滚筒所需的液压; 并且检测压力/时间数据曲线何时指示搅拌筒的偏心行为，由此提供警报或其他指示以确认在卡车中硬化的混凝土堆积是不可接受的。本发明的堆积检测方法和系统不需要使用自动坍落度监测系统，但是可以结合具有良好结果和优点的这种系统来实施。
