Exercise:
1st Introduction to training, safety training in the laboratory of building materials,
technical standards. Theory testing of aggregates for construction purposes - Sampling
aggregate, aggregate moisture determination - oven, 105 ° C, 20 ° C, specific
mass, density, bulk density, moisture, water absorption, porosity,
porosity, grain size, grain size curve.
2nd Laboratories-Testing aggregates - bulk density, density in the measuring
cylinder in the pycnometer and hydrostatic scales + calculation of void,
sample preparation for grain. Protocol 1
3rd Laboratories - Testing aggregates - aggregates of particle size, determination
aggregates of fine particles, shape index. Protocol No.2
4th Theory - the design of concrete mixtures by using BOLOMEY, including control
excess cement paste, water / cement ratio and the amount of solid particles in
size of 0.25 mm. Program 1: Designing a concrete mix by Bolomeye
5th Theory testing fresh, hardened and aerated concrete - manufacturing process
specimens and their handling, consistency tests, bulk
mass airflow detection, manufacturing process and test specimens
determination of strength properties of hardened concrete, the depth of percolation test
pressurized water.
6th Laboratory-production of test specimens without plasticizer and plasticizer,
test the consistency of fresh concrete (slump, slump cone), survey
amount of air in the concrete mixture. Protocol No. 3
7th Laboratory-production of aerated concrete LP test consistency of fresh
Concrete, establishing the amount of air in the concrete mixture. Protocol No. 4
8th Theory of Cement and Mortar - sorting, classification, physical and mechanical tests
cements.
9th Laboratories - testing cement - determination of normal density cement slurry,
start setting time of cement paste, the production of test specimens for strength
cements. Protocol No. 5
10.Laboratory - testing mortar - overflow, additional sample
tests (Marsh, decantation, erosion). Determination of strength properties of concrete
Exercise No. 6 Determination of the depth of water seepage pressure. Protocol No. 6
11.Laboratory - Non-destructive methods for concrete strength by the Schmidt
hammer and verify the homogeneity of the concrete using ultrasonic waves. Verification
location of reinforcement in concrete, its diameter and depth of storage. Determination
strength properties of concrete exercises and progress tests No.7.
