Method for delivery of cementitious materials and waste removal thereof

Abstract

A method of delivering a necessary amount of a component for a cementitious product to a construction site, depositing the component into a container, using the component to make the cementitious product, and then retaining residual component and material resulting from rinsing the mixing equipment. In its preferred embodiment, an empty plastic container is delivered to the site, the deliverable component is sand, and the cementitious product is stucco. The amount of sand that is needed for stucco is determined and delivered to the plastic container via conveyor belts from sand trucks sitting in the street. The sand is used to mix the stucco in mixers present at the construction site, as known in the art. Once the stucco is mixed, the mixing equipment is rinsed with water and the washout effluent is deposited in the now-empty plastic container. The plastic container is then sealed and picked up with a crane sitting in the street and emptied at an accepted waste facility.

1 . A method of material handling comprising:
 a) delivering a container to a construction site;   b) adding a component of a cementitious product to the container by conveying the component to the container using a conveyor system;   c) making the cementitious product from the component; and   d) retaining waste from making the cementitious product in the container.   
   
   
       2 . The method of  claim 1  wherein the conveyor system is remote from the container. 
   
   
       3 . The method of  claim 1  further comprising removing the container retaining waste from the construction site. 
   
   
       4 . The method of  claim 1  further comprising sealing the container substantially closed. 
   
   
       5 . The method of  claim 1  wherein making the cementitious product further comprises using a mixer. 
   
   
       6 . The method of  claim 4  further comprising rinsing waste from the mixer into the container. 
   
   
       7 . The method of  claim 1  wherein the component is sand. 
   
   
       8 . The method of  claim 8  wherein the cementitious product is stucco. 
   
   
       9 . The method of  claim 1  wherein the container is substantially plastic. 
   
   
       10 . The method of  claim 1  wherein the container is substantially watertight. 
   
   
       11 . The method of  claim 1  wherein the container further includes a cover. 
   
   
       12 . A method of material handling for a residential construction project on a construction site that includes an area from which heavy equipment travel is prohibited, the method comprising:
 a) determining the amount of a cementitious component necessary to build the residential construction project;   b) delivering an empty container to the construction site;   c) adding the determined amount of the component to the container by conveying the component to the container using a conveyor system from outside the prohibited heavy equipment travel area;   d) making the cementitious product from the component using a mixer; and   e) rinsing waste from the mixer into the container;   f) sealing the container substantially closed; and   g) removing the container containing waste using a crane from outside the prohibited heavy equipment travel area.   
   
   
       13 . The method of  claim 12  further comprising moving the determined amount of the component to a mixer. 
   
   
       14 . The method of  claim 12  further comprising emptying the waste from the container. 
   
   
       15 . The method of  claim 12  wherein the component is sand. 
   
   
       16 . The method of  claim 15  wherein the cementitious product is stucco. 
   
   
       17 . The method of  claim 12  wherein the container is substantially plastic. 
   
   
       18 . The method of  claim 12  wherein the container further comprises a cover. 
   
   
       19 . The method of  claim 12  wherein the container is substantially watertight.
