摘要： The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (“NDR”) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.

摘要： The present invention provides a method for making sand compositions wherein manufactured sand particles are pretreated with a clay-mitigating polycation and blended with natural sand particles that have washed to remove fines such that at least 90% of the natural sand particles are retained on a 75 micron sieve. Methods of the invention also involve the use of the blended pretreated sand for making concrete wherein the sand is combined with cement, a polycarboxylate type dispersant, a further amount of clay-mitigating polycation compound, and at least one hydryoxyl or hydroxyl carboxylic acid or salt compound.

摘要： Method and system for monitoring slump flow of hydratable cementitious material such as wet concrete in a rotating mixing drum. Whereas prior art methods use a single value of the hydraulic pressure for turning the drum (such as the average value) and correlating with slump values using the vertical drop measurements of the standard slump test (e.g. ASTM C 143-05), the present invention involves analysis of values corresponding to slump flow of concrete samples, preferably having slump flow values of 16-36 inches when measured using standard slump flow tests (e.g., ASTM C1611-05).

摘要： A sprinkler assembly includes a sprinkler housing including at least one fluidic- circuit-receiving port carrying a fluidic insert configured to receive irrigation fluid and project the irrigation fluid in a desired spray pattern. The fluidic insert is held precisely in place by a retention ring adapted for insertion into the housing's interior lumen to provide a snap or friction fit within the housing while engaging and retaining the fluidic insert against impact forces from inrushing fluid surge. The retention ring fits entirely within the sprinkler assembly's housing or package, and is economically molded as a one-piece component, and does not have any effect on external appearance of the sprinkler assembly or any adverse effect on the fluidic insert's spray pattern.

摘要： The invention provides ‘thixotropy’ monitoring, by measuring the reversible, time-dependent reduction in viscosity occurring when concrete is subjected to mixing, and employs a mixing drum and conventional slump monitoring equipment as used on ready-mix trucks. In one embodiment, the drum is rotated until concrete is completely mixed; the speed is altered, such as by increasing it to a predetermined level; and the energy required to rotate the drum (ER) is monitored; the maximum (ER-MAX) and minimum (ER-MIN) values are recorded in computer memory; and these values are compared to pre-determined (target) values. Rheology factors (including viscosity, yield stress, and/or thixotropy) can be adjusted accordingly by adding liquid component(s) into the mix. This method, suitable for delivery of highly fluid concrete speed such as SCC, can involve transit and placement rheology targets during monitoring.

摘要： The invention relates to a method and system for monitoring and adjusting both air content and rheology (e.g., slump, slump flow) properties of a hydratable concrete mix contained within a concrete mixer. The system simultaneously tracks dosage of both rheology-modifying admixture (e.g., polycarboxylate polymer cement dispersant) and air control agent or “ACA” (e.g., air entraining agent) by reference to at least four nominal dose response (“NDR”) curves or profiles, which at least four NDR profiles are based on the respective behaviors of each of the ACA and rheology-modifying agent on air content and rheology.
